Lexus IS vs BMW Alpina B7

What's the difference?

Smooth, cosy, quiet, the IS looks and feels better than ever, but without a doubt this hybrid version is a car best suited to cruising the dense metropolis of Chiba at midnight more than it is carving up a bunch of S-bends in the Australian countryside on the weekend.

While that might still limit its appeal for fans of German sports luxury sedans and place it further from the original IS’s ambitions, it does offer an intriguing efficiency and luxury focused alternative, without the compromises brought by rivals with more sporting intent. In a way then, the IS 300h perhaps inadvertently best embodies what Lexus is as a brand.

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.

Look closely and quite a lot has changed. This is really a story of doing a facelift right. Lexus has kept all the great-looking bits of the car that launched in 2013, like its striking side profile and angular accents, while dumping most of its least popular elements like the spidery front light-clusters and busy front splitter, in favour of something more refined and conservative.

It even adds some new flair in the rear three-quarter, with dramatic LED light-clusters working their way into a trendy highlight strip across the boot lid.

These changes all add up for a much tougher, sportier, and nuanced design compared to the outgoing car. One that manages to make an eight-year old design look as contemporary as ever.

I even liked our test car in its plain black shade, although I'm less sure about those conservative-to-a-fault, almost Camry-esque alloy wheels.

On the inside, sadly not a whole lot has changed. The busy design looked dated when this generation of IS launched in 2013, and it still looks dated now.

The visual assault of buttons, toggles, displays, textures, and trims is a lot to take in, and makes the cabin feel smaller than it is.

It probably didn’t help the sensory overload of this car’s interior as I hopped out of the stripped-back interior in the Tesla Model 3 I had the week before.

My less-than-impressed brother, a student of design, described the IS’s interior best when he told me “It’s a bit maximalist, don’t you think?”

If nothing else, at least Lexus hasn’t blatantly imitated anyone else when it comes to its interior, but the brand remains firm on dorky design items like the laptop touchpad, redundant drive-select dial, and odd vacant panels under the climate unit which do it no favours.

A welcome upgrade for the 2021 model year is the new media screen, a highlight piece perched atop the dash. It’s bright, has excellent contrast, and doesn’t seem to fall victim to glare.

The Apple CarPlay support I used was seamless and sharp and made the most of the available real-estate in its widescreen layout.

I somehow didn’t mind that the instrument cluster in this base car is analog. It almost suits the IS’s character better than a digital set-up would. Also offered is a small information display between the dials which I used for monitoring the hybrid drive.

A final note on the IS’s design. The fit and finish is quality, inside and out. It leaves you with an impression that this is an immaculately built vehicle, one that should be a must for all luxury cars, and always a strong point for Lexus.

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.

Well, the IS is a sedan, so it doesn’t quite have that high-riding appeal of an SUV, and for this update it has even leaned further into its low-slung proportions with a roofline that descends a further 15mm and a boot lid which is 31mm lower overall.

As with the previous car, the interior is quite closed-in thanks to that busy dash design and large centre console. Rather than feeling claustrophobic though, it is best described as cosy, with lots of plush finishes throughout the doors and centre stack befitting a luxury nameplate.

Adjustability is great for the front two occupants and there are two large bottle holders between the seats, a large but shallow console box under the armrest, bottle holders with adjoining bins in the doors, and a smallish glove box.

That’s about where storage ends though, with no extra trays or bins in front of the oddly placed shifter, just an awkwardly finished plastic panel where it feels like a little tray or storage cutaway should be.

The touchpad for operating the media screen joins an unnecessary drive-select cluster in eating up centre console space where there could be more storage.

The rear seat is quite limited on space despite being lavishly trimmed. I fit behind my own (182cm/6'0") driving position with little knee or headroom to spare.

Again, it’s cosy and very comfortable, but if you're taller or wider than me you may run into issues.

The centre rear seat is all but useless for adults, with the IS’s rear-drive architecture necessitating a huge transmission tunnel that almost comes as high as the seat base itself.

Storage is limited to pockets on the back of the front seats, small bins in the doors that double as handholds, and a drop-down armrest with two bottle holders.

There are no power outlets for rear passengers, but there are dual adjustable air vents.

Boot space is 450L which is a little small for the class. It’s impressive the hybrid only managed to lose 30 litres compared to petrol-only IS variants, though, so best to count your blessings.

The largest CarsGuide travel case easily fit in the wide but short available space.

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.

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.

Rivals to the B7 include the Mercedes-AMG S63, which lists for $375,000, the $331,700 Audi S8 and even the Bentley Flying Spur, which almost matches its price at $389,500.

The IS 300h does stand out from the luxury sedan crowd by offering a hybrid drivetrain at a reasonable price. Some rivals offer plug-in options further up the price scale cementing them as a niche option, but the beauty of this Lexus is its very mild $3000 price jump over the base petrol car.

The base car’s 2.0-litre turbo is dumped in favour of a 2.5-litre non-turbo Atkinson-cycle four-cylinder hybrid set-up similar to the one proving popular in the Toyota Camry and RAV4.

The petrol engine produces 133kW/221Nm on its own, and the electric motor produces 105kW/300Nm. Toyota says the “combined system output” of this is 164kW.

Either way, that's less than the base 2.0 turbo. The 300h also swaps out an eight-speed torque converter automatic in favour of a continuously variable transmission. Rare in a rear-wheel drive car.

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.

As you might hope this hybrid IS has an astoundingly low official/combined fuel consumption rating of 5.1L/100km.

I was pleased to find that after a week of mainly urban driving conditions, our IS was returning a figure of 6.9L/100km. Not bad at all, especially for a class where fuel consumption can get a little out of hand with turbocharged engines or V6s.

Of course, using the hybrid system to your advantage over the long term will get this number much lower, as I discovered on my long-term test of the Toyota Corolla hybrid which essentially uses a smaller version of the same system.

Certainly, if fuel consumption is a high concern, you’re better off with this car than the top-spec V6 (IS 350) which will easily see consumption enter double digits.

Lexus recommends a minimum RON rating of 95 for the IS 300h, and the fuel tank is 66 litres regardless of variant, giving the hybrid an impressive theoretical range of around 1000km.

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.

There is no doubt the IS 300h is capable. You can feel it through the car’s solid rear-drive underpinnings, silky smooth steering, and reactive chassis.

What this car doesn’t offer is excitement in quite the same sense as many of its rivals. That’s down to this hybrid’s drivetrain. It just doesn’t have that powerful follow-through in the same way turbocharged BMWs or Audis or Mercedes do.

If it’s that 'sports luxury' experience you’re seeking better off looking to the base 2.0-litre turbo or the V6 and their eight-speed automatics.

The 300h does offer something a bit different. The gentle refined efficiency of Toyota’s signature hybrid system in a luxury rear-drive package that’s smaller than this car’s ES bigger brother.

While it may feel capable thanks to the lighter suspension components and altered track that the brand has committed to for this update, the hybrid drive matches this car’s softer character brought about by its gentle suspension tune and light steering.

This is an easy car to drive around a city, it filters out bumps nicely, while offering near silence in the cabin and breezy steering for every day scenarios like manoeuvring in tight parking lots.

The CVT auto and instantaneous torque available from the electric motor make it best at traffic speeds, being both reactive and predictable, with silent acceleration when inching forward at the lights or cruising along at 50km/h.

As you might expect though, the wheezy Atkinson cycle engine and CVT conspire for a noisy and less than engaging experience under heavy acceleration.

It’s not as though you’re rewarded with particular vigour either, with this combination being a bit sluggish when a lot is asked of it.

It loses its reactivity and refinement at higher speeds or in the corners on country roads as the transmission elastically tries to keep up with the demands of the driver.

Still, few luxury sedans are quite as purpose-built for the toils of a city, and if you want to get drawn into this car’s hybrid drive antics, it’s easy to make a game out of saving fuel by trying to rely on its low-speed electric motor capability.

Really then, it leans into its urban luxury appeal. A luxury sedan for the streets of Tokyo. An ideal car in this class for the urban environment.

If you don’t care for the thrill of a turbocharger or frequently seek to explore the twists of your nearest B-road, you could do worse than the comfort and ambiance the 300h offers.

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.

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.

Lexus gets slightly ahead of the luxury pack with an extra year of warranty. While BMW and Audi still sit on three, Lexus offers four, but it is limited to 100,000km and is still outdone by Mercedes-Benz and Korean newcomer, Genesis, offering five-year/unlimited kilometre promises.

The IS has capped price servicing fixed at $495 for the first three years of ownership with roadside assist, and the brand will even pick up and drop off your car, or offer a free loan car during every 12 month or 15,000km service.

It’s worth noting that German rivals offer pre-paid service packages out to five years, and Genesis is trying to make a splash with free servicing.

Lexus does offer a luxury ownership program dubbed ‘Encore’ which includes invites to experiences and certain partnerships with restaurants and the like to keep potential owners enticed.

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.
