- Australia's speed limits
To say Mercedes-AMG is popular in Australia is like saying the young people are fond of Drake, or that football fans seem to appreciate Ronaldo’s skills.
Per head of population we buy more of the three-pointed star’s go-fast specials than any other country on the globe. Typically, between 15 and 20 per cent of all Mercs sold here are of the AMG variety.
The ‘43’ suffix appeared on C and E Class variants, meaning a 3.0-litre, twin-turbo V6 had been slotted under the bonnet, providing enough grunt for day-to-day enjoyment without the hardcore edge of a big-banger V8.
But the boffins at AMG’s Affalterbach HQ can’t seem to help themselves because the E 43 has been replaced by, you guessed it, the gruntier E 53.
Powered by a 3.0-litre, in-line six-cylinder turbo engine, the 53-series delivers close to 15 per cent more power and a huge dollop of extra torque courtesy of its tricky ‘EQ Boost’ starter/alternator system.
So, has the civility and relative efficiency of Merc-AMG’s only slightly psycho E Class models been maintained, or has another beast been released?

BMW Alpina B7
You know when you're walking along the footpath and you come to a soft spongey bit that the council have put in around a tree and your mind goes: "Whoah, the ground is bouncy but it looks just like bitumen?!"
Well that's the kind of response you'll get from people when they think they're looking at a regular BMW 7 Series, only to have their world go a bit bouncy when they see the Alpina B7 badge on the back of this car as you're overtaking them at Warp Factor 9000.
And you will be overtaking them like a blur because, thanks to the elves at German tuning house Alpina, the B7 is hugely fast for a five-seat, 5.3m-long, 2.2 tonne limo. But then the B7 is fast for any type of car of any dimensions, because with its 330km/h top speed this beast will outrun a McLaren 570GT. Yes, seriously.
Based on the BMW 750Li long wheelbase, the B7 begins life rolling down the same production line as a regular 7 Series. Alpina then goes on to make so many changes to the engine and chassis that the German government requires the BMW VIN to be replaced with a new one.
Ready to find out more? Well there's so much to see here that things may go a bit weird and bouncy again. Be prepared.

The Mercedes-AMG E53 is a supremely refined and satisfying performance/luxury package. For those who want the practicality and style of a high-spec E-Class, with an extra performance boost (but not the full-fat V8 drama) it’s got to be an appealing option. Plus, the high-tech hybrid drivetrain is brilliantly executed and seamless in operation.
Does the E 53 AMG do enough to warrant the hallowed Affalterbach seal of approval? Tell us what you think in the comments section below.
BMW Alpina B77.9/10
The BMW Alpina B7 is a special car destined (like all Alpinas) to be a collector's item, due to its rarity and exclusivity. I asked Alpina just how many current model B7s there are in Australia and the answer was "less than five", which is just as mysterious as most people find the car in general.
The B7 is fast – too fast to enjoy legally on Australian roads – but it is also supremely comfortable and well appointed. For Alpina fans lucky enough to be driven in on,e this would make for a truly rare and niche way to be chauffeured.
Is the BMW Alpina B7 the ultimate fast limousine? Tells us what you think in the comments section below.
Keen car-spotters will pick the E 53 courtesy of its ‘twin-blade’ radiator grille (in silver chrome) with black mesh insert in place of the standard E-Class ‘diamond’ version, and a distinctive ‘A-wing’ front apron design.
AMG-specific side sill panels link the front fascia to a rear treatment including a high-set diffuser panel and quad exhaust tailpipes finished in high-gloss (black) chrome.
The interior doesn’t vary dramatically from other high-end E-Class variants, the biggest differences being grippier, leather-trimmed sports seats, dark ash wood trim on the dash, console and doors, plus an ‘AMG Performance’ steering wheel trimmed in nappa leather.
A twin (12.3-inch) screen ‘Widescreen Cockpit’ media and instrument array includes the ability to scroll through an AMG-specific digital display, scrollable through ‘Classic’, ‘Sporty’ and ‘Progressive’ configurations.
Via the AMG menu it’s also possible to call up read-outs including engine and transmission oil temp, acceleration (longitudinal and lateral), engine outputs, turbo boost pressure, tyre temps and pressures, as well the current vehicle set-up.
BMW Alpina B77/10
This is a good place to start because the B7 looks just like the 750Li it's based on, until you see the first tell-tale signs that it's not one.
There's the front wing with Alpina lettering and the boot-top spoiler, the graphics, which run the length of the car, and the 20-spoke wheels with Alpina badging.
This is late '70s, early '80s styling at its best (and possibly worst), but these special cars can pull off the irony-free look because this is how Alpina BMWs have rolled since 1975, when the E21 320-based Alpina A1/3 was launched.
BMW badges have been left on the bonnet and boot, but there's Alpina B7 BiTurbo lettering in place of the 7 Series identifier.
Most people walked by it in the street thinking it was just a big BMW, others scratched their heads wondering what I'd done to my big German limo and a handful almost dropped to their knees in praise and wonderment at spotting a rare beast like this in the wild.
These people all had their own Alpina stories – one was the third generation of an Alpina-owning family. You become a member a small and passionate club when you buy into this rarefied brand.
The standard B7's cabin is close to identical to the luxurious interior of the 750Li, save for Alpina-embossed stitching in the headrests of the soft, leather seats, the virtual instrument cluster and the Alpina plaque on the centre console denoting the build number.
The B7 is long, low and wide at just under 5.3m end to end, 1.5m tall and 1.9m across. A 3.2m wheelbase means cabin room is more than just spacious.
The B7 rolls off the Dingolfing production line in Germany and is then handed over to Alpina's facility in Buckle, where significant changes take place. Read on to find out how the B7 is different from a regular 750Li.
Despite availability in sedan, coupe and cabriolet form, the E 53 launch drive program focused exclusively on the coupe and cabrio.
Like all E-Class models the E53 offers plenty of space up front, as well as a generous, lidded console box incorporating multiple USB ports.
A second flip-top section in front of the media controller houses a pair of cupholders, oddments space and a 12-volt power outlet, plus there’s a medium-size glove box, and the doors feature long bins including big bottle holders.
Rear room in the sedan is typically E-Class generous, with three adults across the back seat a genuine option on shorter journeys.
Adjustable air vents are welcome, and a fold-down armrest houses two cupholders and a lidded bin, with another two USB ports provided. Door pockets incorporate bottle holders and there are map pockets on the front seatbacks.
The sedan’s boot capacity is 540 litres, more than enough to swallow a pram and accompanying baby ‘stuff’, or our three-piece hard suitcase set (35, 68 and 105 litres). And the 40/20/40 split-folding seat back liberates yet more space.
Backseaters (two only) in the coupe and cabrio are well catered for. Legroom is surprisingly substantial, although with the roof up, at 183cm, headroom for me was just adequate. With the cabrio’s roof down however, that improved considerably. Worth noting that sensors in the front seats’ adjustment system stop them from hitting a rear passenger’s knees. Nice.
In terms of storage and convenience, there’s a pair of cupholders between the seats, adjustable air vents, map pockets, and some oddments space near the outside armrests.
Boot capacity in the coupe is 425L and 385L in the cabrio, with the rear seat splitting and folding to offer through-loading space. An electrically controlled, retractable separator in the soft-top’s boot defines the space filled by the roof when folded (which still leaves 310L).
Tyres are run-flat on all variants, so don’t bother looking for a spare of any description.
BMW Alpina B78/10
The B7 is a five-seater limousine although with the fold-down rear centre armrest which houses the media control panel the back is really set up to carry two.
That 3.2m wheelbase means cabin space is enormous. At 191cm tall I can sit behind my driving position with about 30cm between my knees and the seatback. Those rear doors open wide and the entrance is huge, making entry and exit almost as easy as just walking through a doorway. The air suspension also rises and lowers the B7's ride height for better access.
Storage is excellent, with two cupholders and door pockets for rear passengers, along with the area inside the centre armrest.
Up front, the driver and co-pilot have a deep centre console storage bin with split-opening lid, two cupholders and door pockets.
Luggage space is good, with a 515-litre boot.
Price and features
Pricing for the Mercedes-AMG E 53 ranges from $167,129 (plus on-road costs) for the sedan, through $172,729 for the coupe, and $181,329 for the cabriolet.
Then the cabrio is something of an outlier, with the BMW M4 Competition ($165,615) again a smaller but faster and cheaper option. In the hunt for other performance-focused 2+2 convertibles, you’re into the entry-point of Porsche’s 911 line-up with the Carrera Cabriolet ($248,350) representing a close to $70k premium.
All variants are suitably well equipped. On top of the standard performance and safety tech detailed in later sections, the E 53 is fitted with dual-zone climate control, 13-speaker Burmester audio (including digital radio and Apple CarPlay compatibility), keyless entry and start, nappa leather trim, sports seats, ‘AMG Performance’ (flat bottom) sports steering wheel (also trimmed in nappa leather), adaptive LED headlights (plus active high beam), and 20-inch alloy wheels.
Also included are the Widescreen Cockpit display (twin 12.3-inch screens covering multimedia and instruments as well as ‘Linguatronic’ voice control), sat nav, ambient interior lighting (64 colour options), active cruise, a configurable head-up display, electric front seats (heated with memory), wireless phone charging, wood grain interior trim, electric steering column adjust, rain-sensing wipers, and a panoramic sunroof.
All that stacks up well for a contender in this part of the market. You pay the big bucks, you get all the fruit.
BMW Alpina B77/10
The B7 lists for $389,955, while a 750li is about $319,000. At this level, $70K seems like a downright reasonable premium to pay for a faster, more powerful, better handling and comfier version of the 750Li.
In this case you're paying more but getting more, although standard features are close to identical. There's adaptive LED headlights, head-up display, night vision with pedestrian detection, a 10.25-inch touch screen up front and two screens in the second row for TV and other media functions.
There's a reversing camera, sat nav, harman/kardon surround stereo and Apple CarPlay. There's leather upholstery, seat massagers in the front and rear, four-zone climate control, heated and ventilated front and rear seats, front and rear parking sensors, auto tailgate, sunblinds for the rear and rear-side windows and proximity key.
The safety features are listed in the section below, and that list is also impressive.
Engine & trans
Already used in other AMG models, including the entry-level version of the just-released flagship GT 4-Door, the E 53’s (M256) in-line six is a 3.0-litre all-alloy unit featuring direct-injection and a single turbo, supplemented by an electric compressor (turbo if you prefer) which builds up charge pressure prior to the main turbo coming on song. Turbo lag, be gone!
The EQ Boost starter-alternator is housed in an electric motor fitted between the engine and transmission, driving a 48-volt electrical system to support the additional compressor as well as the car’s traditional 12-volt functions (lights, cockpit, multimedia and other control units) through a DC/DC converter.
Maximum torque (520Nm) is available from just 1800rpm all the way to 5800rpm, with peak power (320kW) taking over at 6100rpm. But the EQ Boost’s hybrid party trick is the ability to drop in a brief full-throttle burst of 16kW/250Nm. Whoosh.
Drive goes to all four wheels via a nine-speed dual-clutch auto transmission and an AMG Performance turned version of Merc’s ‘4Matic’ all-wheel drive system, using an electro-mechanical clutch to distribute torque between the permanently driven rear axle and variably driven front axle.
BMW Alpina B79/10
Alpina takes the 4.4-litre twin turbo V8 from the BMW 750Li and rebuilds the engine by hand. Alpina fits its own turbochargers, air-intake set -up, high-capacity cooling system and Akrapovic quad exhaust. Output is 447kW and 800Nm – an increase of a whopping 117kW and 150Nm over the 750Li's grunt.
It's interesting to note that the V12-powered 760Li has a smidge more power, at 448kW, and the same torque output as the B7.
How fast is the B7? Supercar fast – the B7 has a top speed of 330km/h, which will see it outrun a McLaren 570 and almost keep up with a Ferrari F12. That's quite incredible for a 2.3-tonne limousine with three TVs on board. A 0-100km/h time of 4.2 seconds is also hugely impressive.
In comparison, a 750Li has a 0-100km/h time of a not-too-shabby 4.7 seconds, but the car is electronically limited to 250km/h.
An eight-speed automatic transmission shifts gears smoothly, although a little slowly in Normal mode, while Sport and Sport+ add urgency and harder shifts.
Finally, the B7 is all-wheel drive, and those rear wheels are designed to steer slightly for better cornering performance.
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is line-ball for sedan (8.7L/100km), coupe (8.8L/100km), and cabriolet (9.0L/100km) variants, emitting 199, 200, and 204g/km of CO2 respectively in the process.
Start-stop is standard, minimum fuel requirement is 95RON premium unleaded, and you’ll need 66 litres of it to fill the tank.
BMW Alpina B77/10
The B7 is probably not the car to own if you're concerned about either fuel prices or emissions, but then the twin-turbo V8 may not be as thirsty as you'd think, with Alpina stating that, after a combination of urban and open-road driving, you should only use 9.6L/100km.
My time in the B7 saw me double that usage but this could have had something to do with me turning off the stop-start system and driving in Sport mode constantly.
It only takes a few kilometres behind the wheel of the Mercedes-AMG E 53 to recognise that it fulfils its job description pretty well.
With claimed 0-100km/h acceleration sitting in the mid-4.0sec zone (coupe 4.4sec, sedan/cabrio 4.5sec) it’s fast, but not brutal. It growls without rising to the full-blown roar that’s become the aural signature of the current 63-series AMG V8s.
But don’t take that to mean meek and mild. It’s properly rapid and the sports exhaust, particularly with the drivetrain mapped to the ‘Dynamic Select’ system’s ‘Sport+’ mode leaves you (and everyone in a 200-metre radius) in no doubt that you’re driving something special.
Dynamic Select allows individual calibration of the engine, transmission, suspension and steering. Around town with everything dialled in to ‘Comfort’ the E 53 is as refined and compliant as any other high-spec E-Class.
Despite the standard 20-inch rims shod with low-profile run-flat rubber (245/35 front, 275/30 rear) the ‘AMG Ride Control’ adaptive damping combines with the overall air suspension system to provide excellent ride comfort.
Find a twisting B-road and push into ‘Sport’ or Sport+’ mode and the car’s character changes distinctly. All 520Nm of maximum torque is available from just 1800rpm right up to 5800rpm. And while that’s plenty, pin the throttle and an additional 250Nm (and 16kW), courtesy of the EQ Boost hybrid system joins the party.
Press on and as peak power (320kW) takes over at 6100rpm you’ll notice the horizon is approaching rapidly. The additional electric compressor means power delivery is beautifully linear, and the hybrid boost is undetectable.
The nine-speed dual-clutch auto is as smooth at parking speeds as it is at maximum attack. Manual changes (up and down) are rapid and positive, accompanied by entertaining blips and bangs from the exhaust in the more aggressive drive modes.
The coupe is the lightweight of the trio, weighing in at 1895kg, with the sedan and cabrio sending the needle roughly 100kg further to the right. But despite that not insubstantial kerb weight, and the all-wheel drive set-up, all feel light and nimble for their size.
While the variable steering adjusts seamlessly as lateral forces increase, no matter which mode is selected, road feel is modest at best. But the AWD system shuffles drive to the right wheel without fuss and power down out of quick corners is satisfyingly solid.
With all this performance, on-tap braking is critical, and the standard set-up is perforated and internally ventilated discs all around (370mm front, 360mm rear) clamped by four piston calipers at the front and single piston floating calipers at the rear. After an ‘enthusiastic’ session on the launch drive they remained progressive and strong.
The multi-adjustable sports front seats are comfy when they need to be, and with the side bolsters adjusted inwards, secure and grippy as G-force builds. Top-notch ergonomics complement this satisfying and well resolved dynamic package.
BMW Alpina B79/10
Who on Earth thinks a BMW 750Li isn't fast enough or comfortable enough, even with all its horsepower, luxurious cabin and technology? Alpina, that's who.
Redevelopment of the 4.4-litre V8 with new turbochargers, a high-capacity cooling system, different air suspension set-up and an exhaust system made by Akrapovic have made this already exceptional car better. Better to drive and better to be driven in.
The ride, even on those 21-inch wheels and low-profile Michelin Pilot Super Sport tyres (255/35 ZR21 on the front and 295/30 ZR 21 on the rear) is incredibly comfortable. I drove it and also had a chance to recline in the back and be chauffeured (by our photographer) and the ride was so composed and refined it was hard to believe I was travelling along some truly awful urban roads with their cracked and pot-holed surfaces.
And it's quiet, too. Which will suit those in the back being transported swiftly from the airport to their next meeting, but if you're after a loud and angry exhaust note then you won't find it in the B7. Sure, from the outside at full throttle the B7 has a menacing growl, but this isn't a BMW M car that will bark and snarl.
See, while BMW's M division makes brutal, loud, high-performance versions of their regular cars, Alpina makes comfortable, stealthy, high-performance ones.
All-wheel drive provides fantastic traction and ensures that grunt doesn't just tear the tyres off those rims when you sneeze on the throttle.
And while the air-suspension is soft and comfortable, adaptive dampers adjust for when the road goes twisty, providing impressive handling for a heavy and long car.
Really, though, the B7 is built for long, endless stretches of roads, and the acceleration beyond 100km/h is almost as startling as that from 0-100km/h, as it wants to push straight past 200km/h towards that 330km/h top speed.
Which, unless you know a good lawyer or happen to be one, will send you straight to jail. Yes, the B7 is probably too much car for Australian roads. Only on a German autobahn would a B7 be fully at home.
I felt like I was given a Melbourne Cup-winning racehorse for a week but could only ride it in my suburban backyard.
You’d expect any current passenger model wearing the three-pointed star to be on the leading edge in terms of active and passive safety, and the E Class range scored a maximum five ANCAP stars when it was assessed in late 2016.
The E 53’s crash avoidance tech includes ABS, EBD, brake assist, AEB, ESC, traction control, blind spot monitoring, lane keep assist, fatigue detection, a surround camera system, tyre pressure monitoring, and traffic sign recognition.
And if a crash is unavoidable all models feature dual front and dual front side airbags, a knee airbag for the driver, plus full-length curtain airbags… even a first-aid kit.
The sedan features three top tether points and two ISOFIX child restraint anchor positions across the back seat, with a two-and-two count in the coupe and cabrio.
BMW Alpina B79/10
The Alpina B7 comes with all of the BMW 750Li's safety equipment – this includes AEB, lane-keeping assistance and lane-departure warning, blind-spot warning, active cruise control, night vision with object recognition, auto parking and surround view camera.
Along with the suite of airbags, there's traction and stability control and ABS, as you'd expect.
The 750Li and B7 have not been given an ANCAP score.
Mercedes-Benz offers a three-year/unlimited km warranty, with 24-hour roadside assist included for the duration. Not exactly leading edge when you think about Kia at seven years/unlimited km and Tesla’s eight-year/160,000km cover.
Scheduled maintenance for the E 53 is set at 12 months/25,000km, and service plans are offered at silver and platinum levels for up to five years/100,000km.
BMW Alpina B77/10
The B7 is covered by BMW's three-year, unlimited-kilometre warranty. Servicing is recommended every 12 months or 15,000km. The B7 is covered by BMW special vehicles servicing plan, which means services are cost-free for the first three years of the car's life.
