Peter Anderson road tests and reviews the Lexus IS350 Sport Luxury with specs, fuel consumption and verdict.
The Lexus IS has carved out a niche in the executive sedan market - some owners would require dynamite to shift them to another brand. With an unparalleled commitment to post-sales service and a reputation for absolutely bulletproof reliability, Lexus hasn't exactly beaten the Germans into submission here in Australia, but it has given them a good fright. If you want to take on Audi, BMW and Mercedes, you've got to bring what Americans call 'your A-game.'

The IS350 is a niche within a niche, though. At this level, the Germans have convinced their customers that forced induction fours or sixes are the go, while Lexus soldiers on with a naturally aspirated V6 and a specification list as long as your arm.

BMW 6 Series
What happens when you struggle to sell an odd-bod, not-quite-a-coupe, sort-of-a-hatchback, almost-an-SUV model? Well, sometimes it gets axed, and replaced with a new model that bears a new name.
That's pretty much it in a nutshell for the BMW 6 Series Gran Turismo, which was formerly the 5 Series GT. It essentially takes the place of the 6 Series Gran Coupe - an alternative to the regular 5 Series sedan that's more attainable than a 7 Series limousine.
Confused? It's not as difficult as all that sounds - you just need to know that this model, the 2018 BMW 6 Series Gran Turismo, is supposed to offer a neat alternative to the go-to family luxury car or SUV.
I spent some time in the entry-level 630i to see if it can deliver on that promise. In fact, I spent more than 24 hours driving the BMW 6 Series GT over the past week, and I don't have a sore back, I haven't been left scratching my head over the intended purpose, I haven't been uncomfortable, and I haven't been left wanting for much.
|Engine Type||2.0L turbo|

The IS350 is a fine car and is edging ever closer to the truly European feel the marque seems to crave. It's also different enough for those who don't want to be a part of the German triad and want to do something different while getting an after-sales experience that's hard to beat.
The thing about the IS is that it feels a little old - the interior tech and naturally-aspirated V6 are a bit 2009. That's not to criticise the car itself because it's beautifully made and if past IS generations are anything to go by, will outlast humanity. The 350 feels, and is heavy. It's a bit thirsty and doesn't quite tick all the boxes many in the sector are looking for. But wow, is it getting closer.
Is the Lexus IS in the running for you? Or does your wallet only speak German?
BMW 6 Series7.6/10
This isn't a car for everyone's tastes, but if you fit in to the buyer group that just doesn't really know what they want in a luxury car, it could be the perfect fit for your family. The 6 Series GT is a practical large prestige car, albeit one that will likely find very few buyers.
Would you consider a genre-bending car like the BMW 6 Series GT? Let us know in the comments section below.
This third-generation IS is, at last, a distinctive looker. The first car was a clean design that aged reasonably well (as did the car - there's still a ton of them kicking around) but the second one seemed a bit timid, a sort of slimmed version of the first car's styling ideas in a bigger body. Things weren't quite right and that car's look has not aged well at all.
The third generation, though, is much more aggressive, more individualistic. The mid-life refresh made the front end look a bit frowny, but the Lexus spindle grille really looks the business even if the headlights appear awkwardly finished. In profile it fits in well with the pack and then it all gets a bit aggro again at the back, with that extravagant downward sweep of the taillights. Pretty, no, memorable, yep.
Inside is less adventurous and, annoyingly, not ageing as well as Lexus might have hoped. The two-storey dash feels a little heavy-handed with its double chin rolls. I can see what the designers were going for, but they missed.
And that chintzy analogue clock in the centre stack. Please. Stop.
There are also too many Toyota-style buttons littering the dash. Having said all of that, the obvious Lexus bits are terrific to touch and use, apart from the entertainment system's click mouse thing. That's a bit of a mess and the screen's software actively works against precise operation.
All is mostly well on the instrument pack except when the sun is coming over your shoulder. The reflections obliterate both of the traditional dials and if you'd already driven, say, an IS200t with the digital dash, you would be asking tough questions about why that instrument set isn't in the top-of-the-range machine.
BMW 6 Series7/10
There is no denying the 6 Series GT looks better than the old 5 Series GT. It isn't as frumpy, it looks more sporty, and to me it appears to have grown into its identity with more conviction than its predecessor.
That said, I don't necessarily like the look very much - it's a bit like a BMW X6 that has been rounded off a little and lowered down substantially. But I can appreciate some of the finer design aesthetics that it offers up: the frameless windows are a nice touch, and the swooping roofline looks smoother than a duck's back.
Other things like the active grille shutters and the air breathers ahead of the front doors are nice functional touches, and to my eye it lives up to BMW's hope of it looking "smooth but muscular". You can get the 630i with either the M Sport package, like you see here, or the more sedate Luxury Line, which is, well, more luxurious looking.
The M Sport styling and equipment package you see in the images here - with M aero kit and 19-inch wheels (ours had been upgraded to optional 20s) - help out with the athletic look of this very big vehicle.
It's huge in fact. The length of the 630i is 5091mm long, it measures 1902mm wide and sits at 1538mm tall, with a lengthy 3070mm wheelbase.
All that equates to a lot of room in the cabin, and what a sumptuous and delightful place it is to be - leather, wood and plush finishes abound.
This is probably the weakest part of the Lexus equation. While front and rear seat passengers enjoy a pair of cupholders per row, there's little in the way of storage for our ubiquitous phones. A centre console bin is provided (from which your USB cable must sprout), but the dash and console are bereft of a good place to stow your phone. Each front door will carry a small bottle but rear seat passengers miss out. The glovebox is a good size and cooled for your convenience.
BMW 6 Series9/10
Now, I said before that this is a bit like an X6, but it has heaps better interior space than that SUV.
As soon as you slide into the driver's seat, you feel like your inside a large car. The cabin space is plentiful, and there's an abundance of storage on offer, too: there's a split-lid armrest between the seats, a pair of cupholders, a phone storage nook with wireless charging, and big door pockets with bottle holsters.
In the back you have access to door pockets, a flip-down armrest with cupholders (that middle part of the seat can fold down completely to allow storage of longer items), and there's excellent room on offer. How many seats in the BMW 6 Series GT? Five - like, five full-size seats.
Because the roofline doesn't rake as sharply as a four-door 'coupe', headroom is excellent for adults (even of the 183cm variety, like myself), and legroom and toe room are equally very good. This is bigger in the back than a 5 Series, but maybe not as plush as a 7 Series… so I guess it makes sense numerically for its nomenclature.
Of course you get climate control in the front (and in the rear if you option it), and the materials are excellent. The media screen is tablet-style, proudly displaying 10.25 inches of high-def real estate that is both touch-capacitive and controllable by way of the central rotary controller with touchpad. And get this - you can even use gestures to control certain elements like volume, swiping and changing tracks… but you have to option that.
The fully digital instrument display is bordered by a set of incomplete dial rings, which is just odd. BMW, back yourself - your buyers can handle just having a digital screen in front of them, particularly when it's as good as this one.
This grandiose hatchback's boot is commodious - with the back seats in place it has a huge 610 litres of cargo capacity, which extends to 1800L with the 40/20/40 seats folded down using the quick release levers in the boot area.
There is no spare wheel (the BMW range is fitted with run-flat tyres) but it does have a secondary hidden storage area under the boot floor for hiding items or stowing wet gear, bathers/swimmers or muddy clothes.
For context, the X6 has 580L seats up, 1525L seats down.
Price and features
The IS range kicks off at $59,340 for the base IS200t but it's not until you're spending $65,390 that you'll find yourself in a V6-powered IS350. Another twenty large will see you in the Sports Luxury we had for the week, at a not inconsiderable $84,160 (although that's $4000 less than a BMW 340i). What do you get for that? Quite a bit, as it happens.
A 15-speaker stereo (with Mark Levinson branding, whoever that is), 18-inch alloys, dual-zone climate control, reversing camera, keyless entry and start, a hefty safety package, active cruise control, LED headlights and daytime running lights, auto headlights and wipers, heated, cooled and electrically-adjustable front seats with three memory settings on the driver's side, sat nav, lots of leather, park assist and power everything including sunroof.
Metallic paint is a breathtaking $1500.
The stereo, sat nav and various functions are controlled from a rectangular click-mouse arrangement reminiscent of a '90s laptop. It isn't great and my impression of the software is that the designers need to go out and buy some Apple and Android devices and learn how modern things work. Or at least have a look at iDrive and MMI. Having said that, the sound is epic, although the radio's insistence on switching to KIIS FM on start-up, no matter which device or station was last used, was irritating.
The sat nav also has some annoying functions that are, mercifully, switchable. The speed camera warnings are helpful and insistent while the incessant school zone warnings were hugely annoying. That's hardly Lexus' fault given there are so many of the things, but the constant 'ding-dong' in urban areas is infuriating and sounds like you're trapped in an airport.
BMW 6 Series6/10
The BMW 6 Series Gran Turismo range starts off with the model tested here, the 630i. It has a list price of $123,500 before on-road costs - and that's whether you buy the M Sport Line or the Luxury Line.
That's quite a lot of money. And while it has a lot of equipment to help justify the cost, the smarter dollars will probably find their way to a more affordable 5 Series.
Standard gear in this spec includes adaptive air suspension with multiple drive modes, a colour head-up display, semi-autonomous parking, adaptive cruise control with steering assistance, auto high-beam LED headlights with LED daytime running lights, DAB+ digital radio, a 16-speaker harman/kardon sound system, a 12.3-inch driver information screen and a 10.25-inch media display with sat nav, Bluetooth and 'BMW ConnectedDrive' online services.
Hey, you even get a panoramic sunroof as standard! Plus there are things like an active rear spoiler, two USB ports and four 12-volt outlets, leather trim, heated front electric seats, electric steering wheel adjustment, keyless entry, push-button start, and an automatic boot.
It also comes loaded with active safety assistance functions - we'll get to that in the safety section below.
Things it's missing at this price point? Well, heated seats are an option, but bundled nicely into the 'Comfort Package' ($3000) which was fitted to our car. The pack includes heated seats front and rear, quad-zone climate control, electric sunblinds for the rear side windows, and electric seat back adjustment. Oh, and BMW continues to gouge consumers $623 for Apple CarPlay (which seemingly didn't work in our car).
The only other 6 Series GT model available is the 640i xDrive, which is again available with the choice of M Sport or Luxury body styling. It's also pretty exxy, with a list price of $148,900, but gets a more performance-focused drivetrain, as well as extra equipment: essentially the Comfort package, plus vented front seats, interior fragrance (eight options), memory settings for the front seats, 20-inch wheels and metallic paint.
Plus the 640i has Sport+ settings - it's probably the wrong car for those - and 'Integral Active Steering' to couple with the all-wheel drive system.
Engine & trans
The IS350's power comes from a 3.5-litre 60-degree V6 producing 233kW and 378Nm. Zero to 100km/h for the 1685kg sedan is dispatched in 5.9 seconds with the aid of an eight-speed automatic transmission driving the rear wheels.
Towing capacity is rated at 750kg unbraked and 1500kg braked.
BMW 6 Series8/10
Under the bonnet of the 630i is a 2.0-litre four-cylinder turbocharged petrol engine, which produces 190kW of power (at 6500rpm) and 400Nm of torque (from 1550-4400rpm). It uses an eight-speed automatic transmission, and is rear-wheel drive.
That may not seem a lot considering the size of this machine, but consider that some of the steamiest four-cylinder hot hatches have nearly the same outputs, and you realise this engine offers up a far-from slouched approach to propulsion.
The 640i xDrive has a 3.0-litre six-cylinder turbocharged engine with 250kW of power and 450Nm of torque. It gets the same eight-speed auto, but as the xDrive naming indicates, it's all-wheel drive.
But this is the one you'd prefer if you want to hit highway speed in a hurry - the 0-100km/h claim is 5.3 seconds, where the 630i takes a full second longer (6.3sec) according to the company.
BMW 6 Series7/10
BMW claims fuel use of 7.0 litres per 100 kilometres, and you'll need to use 95RON premium unleaded when you fill up.
On my trip with the car, I saw about 9.0L/100km across mostly high-speed driving - some freeway, some highway, some country back road touring, and quite a bit of corners and city stuff thrown in as well. I think that's pretty respectable.
What wasn't so great was the lack of premium fuel in some of the 'away from civilisation' places on my route home. Keep that in mind if planning your own GT long-distance cruise.
For some reason, the IS always feels heavy. There's something about the way the car moves that makes it feel chunky. That's not all bad, of course, because it imparts a feeling of solidity and strength, but when you line it up next to a BMW 340i, it tips the scales a further 145kg the wrong way. When you look at it that way, you're always carrying two medium sized people around with you.
It doesn't seem to blunt the performance too much, reaching 100km/h in 5.9 seconds, about eight tenths slower than Beemer with the same number of gears and a torque deficit of almost 70Nm.
Another reason it feels heavy is that the sprint itself is one of the most drama-free acceleration events you'll ever experience. The 3.5 V6 is as silky as they come, as smooth as any in-line six, which have the advantage of not having pistons punching away from each other throwing the engine about.
It's not as sharp on the throttle as the 340i or A4, even when in Sport+ mode, so the Sports bit of the Sports Luxury tag is about thirty percent of the equation.
It does steer and brake with great accomplishment, but there's no life in the chassis, really, so it's best regarded as a luxury car rather than a sporting sedan. The IS has always been thus but with the sad demise of the IS F, there's nothing to really go after the quicker Audis, BMWs or Mercs. You have to lose two doors and move on to the RC F for that.
Ride quality is superb and the cabin is seriously quiet. Rough roads with huge expansion joints and zingy concrete surfaces fade into the background, conversation remains easy with just the stereo to push what little wind noise penetrates the cabin into the background. The adaptive damping must take a lot of the credit for the ride and handling refinement - it's unobtrusive and doesn't suddenly pour concrete into the dampers when you switch things up.
BMW 6 Series7/10
But if you're in BMW's target market - that being older executive buyers who want space and luxury as a priority over thrills at the wheel, you could do a lot worse.
That's because the 6 Series GT lopes along the highway without fuss - the engine easily coping with the demands of overtaking moves, the adjustable drive modes allowing a light steering and wafting suspension feel to wile away the kilometres.
There are 'Comfort' and 'Comfort Plus' modes, but the latter is a bit too spongy and can be boaty feeling. The Comfort setting is made for the highway.
If you decide to deviate from the straight sections, you'll be able to explore a little bit of dynamic range, especially when you dial up the 'Sport' mode, which changes the damper settings, steering weight, throttle and transmission response, and even the digital dials in front of the driver to a more aggressive look.
Our car had the 'Integral Active Steering' setting, which is a variable ratio steering system that includes rear steering - that essentially helps make is more turnable in corners at highway speed, and easier to park at lower speeds. It's difficult to say whether the assistance is excellent or not short of driving a car without the tech, but to this tester it was hard to hide the size and weight (1835kg kerb weight) of the vehicle.
That isn't to say it's clumsy or lumbering - it is actually pretty agile for its dimensions, though it makes a lot more sense on long drives and coastal cruises than it does in the narrow and twisty alpine roads of the Snowy Mountains Highway that I tested it on.
There's good grip from the tyres, and strong response from the powertrain - but if it were my money, and I had to have a 6 Series for whatever reason, I'd be looking towards the 640i model, which has a thumping six-cylinder with 250kW/450Nm - certainly an engine that would be more at home in this car. Plus that model comes with AWD.
Eight airbags (including knee bags for front seat occupants), ABS, stability and traction controls, blind spot sensor, lane departure warning, rear cross traffic alert, auto emergency braking, forward collision detection, brake assist and driver attention detection.
The IS scored five ANCAP stars, the highest available.
The only complaint here is that both lane departure warning and rear cross traffic alert are too polite - a little more information as to what's going on would be helpful.
BMW 6 Series9/10
The BMW 6 Series GT range has a five-star Euro NCAP crash test score based on 2017 testing, but it hasn't been scored by ANCAP.
There's the usual array of airbags - dual front, front side, full-length curtain and driver's knee airbags are included, plus parking sensors all around, and heaps of safety tech including the 'Driving Assistant Plus' package with lane departure warning and lane keeping assist, forward collision warning, auto emergency braking (AEB) front and rear, blind-spot monitoring and rear cross-traffic alert, and adaptive cruise control with stop and go.
That's all great stuff, and so is the 360-degree camera system with adaptive display - so, if you're reversing and you turn the wheel to one side, the image on screen will move, too. It'll also go between a birds-eye view and a backing-up perspective, and that can take some getting used to.
What was less convincing in terms of the user experience was the rear auto braking, which seemed to be scared of the car's own shadow. On multiple occasions the car jammed on the brakes when reversing out of driveways on to empty streets - be it in the normal height, or the raised height setting.
The 6 Series GT has dual ISOFIX anchor points and three top-tether points are there and ready for baby seats or child seats.
The Lexus range comes with a four year/100,000km warranty with roadside assist for the duration. Servicing is every 15,000km or twelve months, whichever comes first.
The ownership experience only loses marks because of the lack of capped or fixed price servicing. Service intervals are well-spaced at 12 months/15,000km but Lexus will only commit to "indicative" pricing after the first service (which is, to be fair, a freebie).
The Lexus experience is legendary - owners with cars well over a decade old still have them collected from their homes come service time. Technically, you may never have to visit a dealer again, just pay the nice person when they comes back with your freshly washed, and serviced car. Or they'll give you a loan car to drive yourself around in for the day.
BMW 6 Series8/10
BMW runs a condition-based servicing plan, which means the car will tell you when it needs servicing. But you can rest assured it won't (theoretically) cost you much, with the brand's 'Service Inclusive' pack. It covers you for basic maintenance as and when required for five years/80,000km. According to BMW, that includes "annual vehicle checks, oil changes, all filters, spark plugs and labour costs for the duration of the package".
BMW offers a three-year/unlimited kilometre warranty plan, and you get the same cover for roadside assistance.
