Jeep Reviews

Building Jeep's iconic brand name on an Italian family-car chassis is the automotive equivalent of RM Williams subcontracting for Victoria's Secret lingerie.

Jeep Grand Cherokee SRT and Audi SQ5 go head-to-head in this comparative review..star {width:135px;}#article-corpus {width:100%; padding-right: 0;}.star {width:135px;}#article-corpus {width:100%; padding-right: 0;}

When I was a young fellow getting seriously into road testing cars back in the 1980s, Brock Commodores were the kings of the Australian roads. On the main straight at Oran Park raceway in Sydney I strove to get standing quarter mile (400-metre) times under 15 seconds from each new Brock as it was introduced, but could never quite manage it.Fast forward to 2013 and I’ve just done acceleration figures on a hot ‘car’ on the drag strip at Willowbank raceway in Queensland. It ran an easy 13.4 seconds up the strip, almost two seconds quicker than the hot Brocks. That 13-second ‘car’ was actually a truck, a Jeep Grand Cherokee SRT to be precise.Like the hot Commodore the SRT had a big-cube V8 engine. While the modified Holden had a capacity of ‘only’ 5.0 litres, the big Jeep had no less than 6.4 litres behind its iconic seven-slot grille.Not only was the Jeep SRT helped by the relentless improvements in automotive technology over the years, it also had the benefit of four-wheel-drive to minimise wheelspin off the line, electronic launch control ensured each of the Jeep’s four tyres got just the right amount of torque from moment to moment through the Quadra-Trac 4WD system. Finally, it was running on sticky tarmac at Willowbank.OK, it had a lot going for it, but the big Jeep SRT was still a two-tonne truck and it was putting down ridiculously quick times. I mentioned the relentless improvements in technology, but the engine of the Grand Cherokee SRT (the acronym for Sport & Racing Technology) is still an old-style Hemi V8 without any overhead camshafts or multi-valves. No, siree, this big 392-cubic inch, 460 powerplant has just two overhead valves per cylinder and they’re activated by old-fashioned pushrods.Where the technology is evident, though, is in a thoroughly modern electronic fuel injection system. The Hemi V8 produces 344kW of power at 6250rpm (big revs for a large capacity V8) and a handy 624Nm of torque at 4100rpm.Fuel consumption? If you need to ask you should be shopping for something else. Despite having an engine that can revert to being a four-cylinder unit in light-duty running this big machine still likes a drink. Expect to be using 12 to 15 litres per hundred kilometres in normal driving, and even more in around town commuting.On the subject of safety, the big Jeep Grand Cherokees have numerous crash avoidance and/or minimisation items. These include Forward Collision Warning with Crash Mitigation; Adaptive Cruise Control; Reversing camera; and ParkSense park assist. The 4WD models also have Hill Ascent Control and Hill Descent Control.Secondary safety sees the protection of seven airbags (multi-stage driver and front passenger); front seat side airbags; curtain airbags; and a driver’s knee airbag.There’s no mistaking the new Grand Cherokee SRT thanks to its sporting body features, with a black, seven-slot front grille. The LED tail lamps have black surrounds. A new design of rear spoiler is integrated into the electronically-operated tailgate. Naturally there are SRT badges, done in the new design for this latest upgrade of the model.Priced at a pretty reasonable $77,000 (plus on-road costs) the hot Jeep Grand Cherokee SRT is something for those who love big and brash stuff in their motoring lives. Grand Cherokee SRT has standard 20-inch Goliath polished alloy wheels, 20-inch split five-spoke Spider Monkey alloys are available as an option.Should you get tired of the sound of the engine, which seems unlikely, the Grand Cherokee SRT has a high quality 19-speaker, 825-Watt Harman Kardon surround sound audio system.Jeep Grand Cherokee SRT uses an exclusive leather interior in two colours combinations – Black Nappa leather with perforated suede and light slate grey accent stitching as standard, and Laguna leather with perforated suede in Sepia with silver accent stitching as an option. Both leather trim combinations are matched with sporting carbon fibre details on the instrument panel and doors.Not only did the big Hemi V8 perform to perfection on the dragstrip, it sounded the part as well. After winning my two drag races against other journos (it’s hard to sound modest when you’re talking about a hotrod like this!) I stood at the start line and enjoyed the big V8 roar as others competed. The way the noise echoed from the concrete side walls was simply magnificent.Out on public roads we loved the sound and feel of the big Jeep, though it has to be said the feel is on the firm side at times on rough and ready Aussie backroads. Near instantaneous acceleration and the fast acting eight-speed automatic transmission made for ridiculously short overtaking distances, making this one a very safe SUV.

The rapidly-rising Jeep range is poised to notch up further success with this month's release of its significantly uprated Grand Cherokee range. Sales of the Grand Cherokee have shot up by 3.5 times since the new generation arrived in 2011 and Jeep dealerships in Oz have doubled from 51 to more than 100.The latest development is the introduction of an eight-speed automatic transmission across the range, subtle styling improvements, better interiors - and the launch of a 4 x 2 version of the Laredo model.Priced at $45,000 drive away, the pretty high-spec Laredo 4 x 2 V6 puts a Grand Cherokee within reach of many more potential buyers.Laredo, also still available as a 4WD, is followed by the Limited, from $51,000, Overland, from $66,000 and the fire-breathing and feature-packed SRT8 at $77,000. The 210kW/347Nm twin-cam 3.6 V6 continues as the standard motor in Laredo, Limited and Overland, with the impressive 184kW/570Nm Italian 3.0-litre turbo-diesel as an option.Limited and Overland also have the option of the 5.7-litre V8, which puts out 259kW and 520Nm, while the high-performing SRT is powered by a 6.4-litre Hemi V8. It's a mighty beast, capable of producing 344kW and 624Nm - and a throaty bellow.The smooth ZF eight-speed auto gives each engine option longer legs and slightly better fuel economy. And there's a bewildering list of 4x4 systems: quadra-trac, quadra-drive, quadra-lift, selec-trac and selec-trac among them. Some raise or lower the vehicle, others let the driver pick a mode suited to sand, snow, mud or rock.Slim, high density bi-xenon headlights with LED daytime running lights, new bumpers and a restyled tailgate are the most visual exterior changes of the new Grand Cherokees, which also get new instrument clusters, new steering wheels with audio, cruise and voice command buttons and paddle shifters.All models have Uconnect voice command with Bluetooth, TFT customisable displays and audio systems that range from a six-speaker kit in the Laredo to nine speakers with sub woofer and 506W amplifier in Limited and an option pack for the SRT that uses 19 speakers and an 825W amplifier. Crazy.The Laredo gets good cloth seats, Limited has leather, Overland uses Nappa leather and SRT luxuriates in premium Nappa. Get the picture?Hill start assist is standard on all models, as is auto-on headlights, seven airbags and a full suite of electronic driver aids. There's loads of room for up to five adults and 782-litres available in the cargo area .Fold down the back seats and cargo capacity increases to 1554litres.We did about 200km in a Laredo in Queensland's mountainous Maryvale region shortly after a major downpour, and never had a moment of bother, irrespective of the gamut of road conditions, including stretches of dirt, mud and some river crossings.The two-tonne SUV coped admirably, the sole niggle being a split second of nothingness on exiting tight corners while the new gearbox consulted its abacus to decide which ratio was needed.That little problem did not affect the SRT, which now comes with Launch Assist, a bit of electronic wizardry that can let the flagship take off as if fired from a catapult. We tried ours out on a drag strip, where it rocketed from zero to 100km/h in 4.8seconds and went on to record 13.4 seconds for the "quarter mile.''At $77,000 it's no wonder Chrysler can't get enough if them. They're about half the price of some of their class competition. It's meaty motor emits a wonderful sound with all the taps open, so why bother with an over the top audio system to drown it out?The SRT does 20.7 litres/100km in the urban area, but has an official average of 14.0 litres/100km. The Laredo's average is 10.1 with the petrol engine, although we didn't come within cooee of that on our brisk up-and-down route, and the diesel uses just 7.5litres/100km.Overall, an impressive line-up; classy, well engineered vehicles, big on street cred, finish and performance.The grandest Cherokees yet.

A decade ago Jeep owners overlooked their vehicles' lack-lustre quality and dubious roadholding manners. They forgave the faults and appreciated the vehicle's single-minded ability to competently cross the most difficult terrain.Time heals a lot of wounds. The latest Grand Cherokee is imposing and attractively sculpted – and while there have been improvements, most people are willing to overlook any imperfections.Chrysler and Jeep quality is improving. It's now up to average which is still less than ideal. But where the car lets you down is in the superficial stuff - the coachwork, predominantly - while the engineering seems to be increasingly more durable.At $65,000 it's a good price for a very well fitted out 4WD that's actually made to go off the bitumen. It's roomy, tows well, has a heap of safety gear, is relatively economical to run - though has no capped-price service program - and has a style that looks as good on top of a dune as alongside a downtown curb.The Overland is the top-spec model but I think there's better value in a mid-range Limited model with the diesel engine at $60,000. If you stay with petrol, the V6 is $5000 cheaper and better value than the optional V8. Be aware that there's a new model coming with upgrades including a more desirable eight-speed automatic transmission.Lovely to look at with a chunky body sculptured with neat chamfers and big wheels stuck hard up at each corner. The cabin is equally as attractive but falls down on closer inspection with average dash panel fit and large, cheap-looking switchgear. Yes, it's workable and hints at being rugged but could be improved. The foot-operated park brake is a Chrysler stable mate and is hard to work in off-road conditions. Beautiful perforated leather seats are comfortable, have heating for front and back and cooling for the front.Electric adjustment - including the tilt/telescopic steering wheel - makes it easy to find the perfect driving position. The heated steering wheel is cool, er, warming. More electrics for the tail gate - with separate lift-up glass panel, which is handy - and the dual-pane sunroof. The liberal space in the boot and the split-fold rear seats give it typical SUV flexibility. The Overland is the most expensive of the Grand Cherokee line-up and offers as much luxury as a top-spec Chrysler 300 sedan.Jeep finds another use for its 210kW/347Nm 3.6-litre V6 petrol engine and creates a wagon with running costs that won't break the bank. The engine is powerful on paper but the Overland's weight curtails most of the enthusiasm. It's mated to a five-speed auto then through a two-speed transfer case with constant all-wheel drive. It gets the upmarket Quadra-Drive II transfer case with an electronic rear diff and a five-mode Select-Terrain dial-up traction program like Land Rover's TerrainResponse. The suspension is an electronic air system that changes ground clearance from 205mm to a monster 270mm. The Overland also has a stack of safety gear and a voice-activated media centre with a touch screen, sat-nav, 40Gb hard drive and 10 speakers.The Overland has one of the most comprehensive safety-related equipment on the market - certainly within its $65,000 price bracket - but only has a four-star crash test rating. It has eight airbags, electronic stability and traction control, all-wheel drive, a full-size spare, roll mitigation, tyre pressure monitoring, blind-spot assist, active cruise control with forward collision warning, park sensors front and rear, a reverse camera, an accident response system that shuts off the fuel and unlocks the doors, plus rear cross-path detection.Jeeps never feel planted on the road. There's always - and this is successive - a new model that has the wishy-washy steering and front suspension quirks that require the driver to make continuous adjustments to maintain the road line. It's almost like Jeep deliberately in-build this vagueness.The 3.6-litre V6 engine is smooth, potentially sparkling and careful drivers can get reasonable fuel economy. But the V6 is let down by drawing on a five-speed auto with a lazy torque converter. It desperately needs the eight-speed unit - that's due later this year - to close up the gaps in the ratios. To be fair, the engine is dragging around a 2.3-tonne dry-weight wagon.Driven gently, it's a very comfortable wagon and aside from the distracted steering, makes for a spacious long-distance cruiser. Off the road this is a true 4WD. It soaks up hard bumps and rarely bottoms the suspension and has a brilliant constant 4WD system that ensures maximum traction.Dial in the terrain on the dash-mounted switch and engine and transmission response, brake aids and even the ground clearance are perfectly adjusted for the conditions. Pick low-range and it's as close to unstoppable as any 4WD. While traction is excellent and assurance that this wagon will go pretty much anywhere, the ride comfort is compromised. The Jeep isn't alone here as any 4WD with a similar air suspension will also produce a hard low-speed ride.Despite a couple of grumbles, this is very competent and given its on-road comfort, makes for a true dual-purpose family 4WD wagon.

The growing popularity of SUVs has seen many of the breed dilute the off-road skill set to accommodate more civilised road manners -- but not this lot.Certainly less agricultural than their forebears, these three examples still have more than enough gumption to gallop down the Gunbarrel Highway or amble along the Oodnadatta Track.The phrase “King Off The Road'' has long been associated with the Toyota LandCruiser and there's nothing to suggest it's a royal fraud.The Japanese brand has built much of its reputation on the back of this beast -- wags will joke that if you want to get somewhere, take a Land Rover -- but if you want to get home again take a LandCruiser.The Toyota's debut was as a workhorse in the 1960s, covering rough ground around the Snowy Mountains Scheme, and its legend has grown from there. The throne is currently occupied by the 200 Series, updated in late 2009.The pricing was a reflection of the demand and Toyota was charging mid-$80,000 for the entry-level GXL wagon. But for towing a caravan, horse float or a boat, there wasn't much that could touch the Toyota's 3500kg braked towing capacity.New vehicle sales figures reflected that, with the LandCruiser regularly outselling Nissan's Patrol by two to one. The Patrol has a long heritage in Australia as well, stretching as far back as the LandCruiser.In 1962, geologist Reg Sprigg and family travelled across the Simpson Desert in a G60 Nissan Patrol, the first vehicle to complete the journey. The Patrol nameplate took hold in the 1980s and has been a part of the 4WD scene ever since.The brand just launched its new model -- with no sign of a diesel engine -- so we'd be inclined to look back to when it had a turbo diesel under its squared-off snout. A left-field choice in this segment is the Jeep Commander, a model that never took off in Australia but had seating for seven, turbo diesel power and the off-road cred that comes with a Jeep badge.There were petrol six- and eight-cylinder options but the 3.0-litre turbo diesel V6, teamed with a five-speed auto, had ample torque and a reasonable thirst. Not a stellar sales performer for the US brand, it fell victim to belt-tightening brought on by the GFC, but if you're not interested in a Japanese giant it might fit the bill.HOT TIPSCheck for signs of water intrusion and rust, as serious off-road expeditions gone awry (as well as recent floods) can have rusty consequences.Diesels are generally more frugal and a lot easier to feed in the Outback, where PULP and ULP can be in short supply.Check the fine print on the towing details, as some 4WDs make big boasts but fall over in the capacity details.2010 Toyota Landcruiser GXLEngine: 4.5-litre V8 turbo dieselTransmission: 6-speed automaticThirst: 10.3L/100kmCARSGUIDE SAYSThe 200 Series took Toyota's full-size diesel 4WD into the realm of the turbo diesel V8, which meant lots of torque, as well as genuine off-road ability and room for eight. Cloth trim, stability control, dual-zone climate control, six airbags and money-can't-buy heritage.2012 Nissan PatrolEngine: 3.0-litre 4-cyl turbo dieselTransmission: 4-speed automaticThirst: 11.8L/100CARSGUIDE SAYSLife in the shadows of more popular 4WDs has kept Patrol prices sharp. Three rows of seating, 17-inch alloys, cruise control, airconditioning and stability control are among the features in this full-size off-roader. It was much cheaper than the corresponding 'Cruiser when new and remains a cheaper proposition in the used market.2007 Jeep Commander XH WagonEngine: 3.0-litre V6 turbo dieselTransmission: 5-speed automaticThirst: 10.5L/100kmCARSGUIDE SAYSThe brand has long been known for building off-roaders -- its heritage dates from WWII. Jeep is not as adept at ergonomic interiors as the Japanese but the brand's charisma tends to offset niggles. A genuine seven-seater that will get off the beaten track when asked.

After some effort, The Speaker of the House and I have convinced our near-five-year-old son that there is no such thing as monsters. I am going to have to tell him I was wrong.There are monsters in real life and I'm driving one - the Jeep Grand Cherokee SRT8, the most powerful, technologically-advanced (that wouldn't be hard), high-performance Jeep ever.Snorting, snarling, stupendously quick and somewhat silly, the SRT8 flies in the face of frugal, fiscally responsible and economical motoring. Bring it, baby.If you like the idea of sitting above the traffic and yet still having the ability to bellow belligerently away from the lights at pace, then this is your bus. At a $76,000 starting price (almost $10,000 cheaper than the preceding model), the hottest Grand Cherokee yet is incredible value for money - an SUV with similar abilities and outputs is going to cost at least twice as much.For not much more than a top-spec Pajero or Pathfinder, the SRT8 has Nappa leather and suede sports seats (heated and cooled),a paddleshifter-equipped sports leather steering wheel, carbon-fibre trim bits, dual-zone climate control with rear vents, rear seat heaters, power-folding auto-dimming and heated exterior mirrors, a powered rear tailgate, a touchscreen-controlled 40-gig hard-drive and USB-port equipped Alpine nine-speaker (10 if you count the subwoofer) infotainment system, Bluetooth phone and audio link, 20-inch forged alloy wheels wrapped in wide Pirelli run-flat tyres, although with a 45-series profile you'll want to steer clear of the rough stuff.There are clever touches like a rechargeable pop-out torch in the boot is a neat and handy touch for any unplanned night roadside stops.What puts the Grand into this particular Cherokee is the 6.4-litre HEMI V8, with an active intake manifold and active exhaust, which produces 344kW and 624Nm of torque - up 37kW and 61Nm (and almost 200kg) over the old car. The clever intake and valve system teams up with the cylinder dropout mode (to run on four of the eight cylinders) to drop fuel use by 12.4 per cent to 14.1 litres per 100km.Body control and ride quality (more so the former than the latter) is controlled by a Bilstein adaptive damping suspension, which offers five modes - Automatic, Sport, Tow, Track and Snow - and the all-wheel drive system shifts drive to the best-suited wheels, although there's no low-range - yet another concession to being a bitumen burner as opposed to an off-road warrior.There's not a great deal of scope for body sculpting when you're dealing with a big boxy off-roader as a starting point, but the SRT8 is certainly heavy with purpose.Lower, with the now-common as muck LED running lights, it is more muscular thanks to body add-ons and venting through large bonnet apertures, the hi-po wagon has dual exhausts at the outer edge of the rear diffuser, which makes towing now feasible to the tune of just over two-tonne braked capacity.The boffins claim the new platform (shared with Mercedes-Benz and Maserati) has played its part in improving torsional rigidity by 146 per cent.You'd think with a long list of safety features it would have blown NCAP away but it's only scored (albeit in standard LHD Grand Cherokee turbo diesel guise) a four-star NCAP rating. Top of the list is an epic set of stoppers - Brembo in origin, the big ventilated discs are gripped by six-piston (up from four) front and four-piston rear calipers, enough force, says Jeep, to give it a 0-160km/h-0 time in the mid-16 second range.Also on the SRT8's extensive safety features list is adaptive cruise control, blind spot warning system, stability control (including anti-rollover function), emergency brake assist with forward collision warning, front and rear parking sensors and a rear-view camera. The spare is an 18in steel, with 245/65 rubber - it doesn't quite match the 20s on the SRT8 but also doesn't quite fit into the temporary spare either.Rain-sensing wipers, bi-xenon headlights, an automatic brake drying system, auto-dimming headlights, trailer sway control, seven airbags (including a driver's knee), a tyre pressure monitoring system, but in a nod to its limited 4WD application the hill descent control is deleted.Ferocious is the first word that springs to mind for several aspects of this car. The engine is feral and powerful, leaving little doubt as to the intent thanks to the active exhaust and living up to the noise with pace. The manufacturer claims five seconds is all it needs to reach the state limit and its own performance computer tows the company line.Not bad for something that tips the scales at 2.3 tonnes, but you pay for such outlandish bouts of right-foot brutality at the pump, with a thirst that can go close to 20 litres per 100km, but it's not like you're shopping this leviathan against a Prius.The weak link in the chain is the five-speed auto, which doesn't always respond with the alacrity of the six-speeder bolted to the back of the turbodiesel - using the paddles is a better option given the high (for a V8) torque peak in press-on driving.Track mode on the adjustable suspension offers good body control but super-rigid ride and the latter doesn't soften as much as it should when the dial is turned back to Auto mode and the runflats probably don't help the ride either. The steering is serviceable - not pin sharp but not vague either, but it feels like it is left alone when the suspension modes are changed.The big, comfortable and well-bolstered seats fight lateral forces admirably - it's the tyres that complain first - but the more-expensive European super SUVs show their class in the corners. The Jeep's stopping power also elicits some expletives - the big Brembos haul the wagon to a standstill remarkably well, giving credence to a claim (not tested on our public roads of course) of a 0-160-0km/h “go to whoa” time in the mid-16-second range.Even moderate braking force can halt this demon from 100km/h in 40 metres, although some extra pedal force can apparently bring that down by another five metres. Unlike its more sedate Grand Cherokee siblings, this is more Mount Panorama than Mount Kosciusko - a deep front spoiler and 190mm of ground clearance, not to mention the absence of low range and the least "off-road" compatible all-wheel drive system mean this Grand Cherokee is unlikely to hop over any rocks.What it can do is blow by a whole stack of purpose-built performance cars from standstill - and probably out-brake some of them as well. A tighter machine than the old one, the rocketship Grand Cherokee is a rough diamond - try going faster in an SUV for the money.

Nissan Pathfinder Ti550 and Jeep Grand Cherokee go head-to-head in this comparative review.

There's something gloriously inappropriate about the new Jeep Grand Cherokee SRT8.In a world where many people spend their lives worried about saying the wrong thing, where whole departments have been established devoted to playing it safe, the big, bad Jeep sends all the wrong signals and makes all the wrong noises but that's why we love it.Producing 10 per cent more power and 10 per cent more torque than its predecessor, the SRT8 is a product of Chrysler's Street and Racing Technology arm  a bunch of crazy guys and gals who spend their days turning Chrysler, Dodge and Jeeps into the equivalent of Olympic athletes.And, like its predecessor, the five-seat Grand Cherokee continues to sit on the same platform as the Benz ML SUV, even though the two have parted company  the chassis is incidentally 146 per cent torsionally stronger.Eager buyers have been stumping up $20K deposits for this vehicle, even before knowing the price. No one would have predicted a $76K price tag $7000 less than the old one. For the price, nothing else comes close. The SRT8 is choc full of equipment befitting a luxury vehicle. It rates highly for safety too, although missing out on a five star rating.It's a 6.4-litre Hemi V8 that delivers 344kW of power and 624Nm of torque, 90 per cent from 2800 revs. The previous 6.1-litre V8 produced 313kW and 569Nm. The engine is hooked up to a five-speed sequential auto with smallish steering wheel mounted paddle shifts. But, given the amount of torque that it produces, they're unlikely to see much use.A rotary control enables the driver to dial in more aggressive settings, with Sport and Track modes. Drive of course is to all four wheels. At 189mm it sits 25mm lower than the already good looking standard model, with LED lights, a deeper front dam and more aggressive stance.Ducts provide air to the brakes and take the heat away from the engine. The car rides on 20 inch alloys fitted with big, beefy 295/45 series Pirellis. They're run flats too, which means if you get a puncture you just keep on driving to the nearest servo even though a full sized steel spare is provided.The adaptive Bilstein suspension is controlled by the Selec-Track system and the stoppers are Brembos, 6-pot at the front and 4 at the rear because if you're going to go fast you need to be able to stop fast too. They certainly haven't skimped with this one.It's rated at 14.1 litres/100km. The rating is helped along by the Multi-Displacement System that shuts down four of the engine cylinders when not required to help reduce consumption by as much as 20 per cent.The twin centrally located Boxster-style exhaust was such a defining feature of the previous model we're sad to see it go. This one still has twin exhausts but the pipes have been pushed out to either side. The good news is that you can now tow a boat (you couldn't before because the location of the exhaust precluded a tow bar from being fitted). It can tow 2268kg by the way.Jeep claims the car will do the dash from 0-100km/h in less than 5.0 seconds. Our best run was 5.2 but the record is 4.8 seconds. It handles too. We were able to put the SRT8 through its paces at Anglesea proving ground outside Melbourne, with glimpses of the new Commodore passing in the background. It's perhaps not as sharp as Porsche's GTS Cayenne through the twisty bits but hey, it costs half as much. In a straight line, however, there's not much in it.Jeep is building only 4000 of these cars worldwide this year. Australia has been allocated just 250 of them, but is hoping to get another 1000 next year. Unfortunately most of this year's allocation is already spoken for.It looks fantastic, it goes extremely well and in this segment represents a real bargain. Start shopping it against the likes of Range Rover Sport, BMW X5 M or the Mercedes-Benz ML63 AMG and it's a walk up start.

When grouped together, there are certain letters in the alphabet that conjure up images of motoring excitement and out-of-the-ordinary performance and handling. Various companies Ford, Holden and Subaru use FPV, HSV and STI respectively for super-tweaked versions of some of their models.Not to be outdone, Chrysler Jeep uses three letters and a number – SRT8 – for its stove-hot offerings. SRT stands for Street and Racing Technology and the latest model to hit our shores under this banner is the Jeep Grand Cherokee SRT8.Jeep’s new $76,000 Grand Cherokee SRT8 has sports-car-like performance, a generous standard-kit inventory and all the practicality of a big family SUV.The new Jeep comes standard with an impressive array of goodies and some of the standout features include great-looking 20-inch alloy wheels shod with P295/45ZR20 Pirelli Scorpion Verde run-flat tyres and superb Brembo brakes. HID headlights and rain-sensing wipers make like safer and simpler.While the Benz ML 63AMG and BMW’s X5 M might seem the new Jeep’s obvious competitors – given that you can buy two SRT8s and have a heap of change for the price of each of the German offerings. But image is everything in the car business and the big Germans are in a league of their own in that regard.Basically it’s a Dodge Challenger (which doesn’t come here) in SUV clothing with a Jeep badge and the beefy brute comes armed with a 6.4-litre hemi V8  boasting 344 kW of power at 6250 rpm a hefty 624 Nm of torque that is on tap all the way from 2800 rpm to 6000 rpm.The result is a 0 to 100 km/h sprint time of five seconds and while people who fork out a $76,000 cheque for the big 2.3-tonne Jeep probably won’t be too concerned, the SUV’s claimed combined fuel-consumption figure is 14.1 litres/100km. That said, it is a 13 per cent improvement on its predecessor.This has been achieved despite the bigger-capacity engine churning out 10 per cent more power and 10 per cent more torque than the old model. To help in the fuel-consumption department, the big Jeep SRT8 has a cylinder-deactivation system that shuts down four cylinders when relaxed driving is the order of the day.The glorious-sounding Hemi V8 is mated with a five-speed automatic transmission and steering-wheel-mounted paddle shifters add to the fun. While the transmission does a perfectly adequate job, it is not one of the SRT8’s finest features. One excellent feature is Jeep’s so-called Selec-Trac system that, via a big console-mounted button, allows the driver to choose from five dynamic modes – auto, sport, tow, track and snow. Trailer-sway control is there for the person who wants to use the Grand Cherokee for towing.Inside you will find adaptive cruise control, Nappa leather and suede seats, satellite navigation, a powered fully adjustable steering column and keyless entry and “go”. Also on the standard-kit menu is a great-to-hold multifunction, leather-wrapped steering wheel, Bilstein adaptive damping, fair-dinkum carbon-fibre interior highlights, a powered tailgate and polished-alloy pedals.In the electronic driver aid and safety departments the hot 4WD Jeep boasts ABS brakes, brake-assist and override, active head restraints, roll mitigation, forward collision warning, a rear-vision camera, a limited-slip differential, stability and traction control, a full suite of airbags including one for the driver’s knees, blind-spot monitoring and an enhanced accident-response system.During an extensive media-launch drive program that included time at Victoria’s Anglesea proving ground, the big Jeep Grand Cherokee proved itself to be a dynamic, great-handling, great-sounding performance car with stopping power as impressive as just about any car I’ve driven.
