2018 BMW Alpina B4 vs 2024 Toyota Supra

What's the difference?

You could almost call the B4 S the anti-M4. It's still fast and practical but from a completely different perspective. It's much more a grand tourer than the M4 and even with the Akrapovic exhaust (usually a byword for joyous, anti-social racket), subtle.

For some, the price won't matter because the Alpina delivers what they want - M4-like straight line performance without the histrionics or the uncompromising chassis. And there's also a bit of that perverse exclusivity of the styling that you won't get anywhere else.

The Toyota GR Supra GT is a superb sports car that’s relatively easy to live with in the city even with the manual gearbox and incredibly fun to drive out where the roads are free from traffic.

Not only is the GT great for the price compared to rivals but it’s the pick of the Supra range.   

Alpina has always had a particular aesthetic that could uncharitably be termed as mid-'80s West German - all set square angles and body graphics. Think David Hasselhoff's Berlin Wall look. The company has never really deviated from adding squared-off body bits to the various BMWs it has rebadged under its long-running agreement.

For the B4S, Alpina adds the signature billion-spoke alloy wheels (only a slight exaggeration), a new front splitter complete with Alpina lettering, a weirdly proportioned boot lid lip spoiler and - not even joking - pinstripes. Like I said, mid-'80s West German. You can still recognise the sleek 4 Series Coupe but perhaps the worst of it is the super-sized, wonky-looking ALPINA B4S on the boot.

Inside is rather more restrained apart from the ill-fitting Alpina plaque under the climate control. Again, it's all 4 Series in here, with the lovely Merino leather liberally applied across the cabin. Less lovely is the wood on the door pulls and console but the door cards have an oddly appealing woven leather which looks and feels good.

Sadly the standard 4 Series steering wheel is along for the ride. There's nothing wrong with it - although the Alpina logo does look out of place - but if I were a product planner, I'd beg for the lovelier M wheel.

Perhaps it’s just me but I think the Supra looks exactly how it should look - like a Hot Wheels car.

Seriously, how good does the back view look? I love the spoiler that angles up like a crazy ski jump and the tail-lights integrated underneath it.

I love the huge rear hunches swollen like they’ve been stung by an enormous wasp. Check out the roof - see how it’s curved? And that bonnet with the vent above the wheel arches, I love the styling of every millimetre of this car.

But my neighbour doesn’t. I pulled up and said, “How good does this look?” And he gave me this stare like I was bonkers.

I don’t know, maybe you and I have the same excellent taste, but if there’s anything I hate it's anything that’s boring.

To me the BMW Z4 ‘twin’ is getting very close to the boring end in the styling department. 

Talking of BMW, the Supra's interior is very BMW from the indicators stalks to the media system and climate control set-up.

It’s a modern and minimalist cabin… if only there wasn’t a cupholder right where my elbow goes. That’s a good place to stop and talk about the Supra GT’s practicality. 

If you're in the front, you're in luck - it's a comfortable place to be, with plenty of leg and headroom. Down back isn't terrible despite the coupe roofline. The two seats are nicely shaped for maximum comfort and separated by an odd plastic tray. The fold-down armrest has two cupholders.

Front seat passengers score a pair of cupholders (bring the total to four for the car) and the long doors will hold a bottle each.

The boot swallows a reasonable 445 litres, which isn't at all bad.

The good news is that if you’re tall like me (189cm) and mainly legs then you’ll have more than enough legroom and headroom because the footwells are impossibly deep and the seats can be lowered to what feels like ground level.

Actually, you are almost at ground height in this car so the bad news if you’re as tall as me you’ll probably have to crawl out of the car on all fours.

The cabin of the Supra doesn’t do the storage space thing well. Sure there are two cupholders but their location is the same place my elbow frequents while changing gears and resting.

The wireless phone charging area is good and easy to access, but the door pockets are as thin as post box slots so if it’s letters you’re storing there you’re in luck.

If it’s anything thicker than that you’ll be left looking around for a place to put your purse or wallet and end up throwing it in the phone charger space if the passenger seat is taken.

You could always ask your co-pilot to hold onto your things which reminds me to tell you that the Supra is a two-seater only. There are no back seats, and there’s no option to have back seats.

If you’re looking for a sports car with rear seats (although space will be limited) for the same money then there’s the Audi A4 45 TFSI and at an even lower price is the Ford Mustang GT.

If you look over your left shoulder while in the driver’s seat of the Supra GT you’ll see into the boot -  there’s no wall separating the cabin from the cargo area. This is handy for throwing a school bag in as I did for my son on the morning drop off, but also means your items may make an unexpected visit to the cockpit if you stop suddenly.

The boot is large for a sports car at 296 litres (VDA) and it managed to fit our large CarsGuide suitcase with space to spare as you can see in the images.

The Toyota GR Supra GT with the manual gearbox lists for $87,380 and you’ll pay the same price for the same car with the automatic transmission. 

Yes, almost $90K might sound like a lot of money for a Toyota (unless it’s a LandCruiser) but it’s actually a bargain considering the GTS grade above costs $10K more and has the same engine plus pretty much the same features apart from a fancier stereo, head-up display and 19-inch alloys (rather than the 18s on this GT).

Also, if you didn’t know already the Supra is a BMW/Toyota joint venture model aligned with the BMW Z4, and if you want the Beemer version with the same engine as the Supra GT you’ll pay $139,800 for it.

So see, it’s a bargain in comparison.

The standard features list of the GT has pretty much everything you need. There’s a proximity key, LED headlights with adaptive high beam, active cruise control, sat nav, wireless Apple CarPlay and Android Auto, a 10-speaker stereo, wireless phone charger, heated and power adjustable seats, shifting paddles and sports pedals. 

Great features, but let down only by a small 8.8-inch screen for your media and nav. Still, that absolutely shouldn’t be a deal-breaker for you.

The rivals? Well, clearly the BMW Z4 which is way more expensive, but also there is the Nissan Z which costs between $70-$80K and is also a hoot to drive.

Add the Ford Mustang GT to your research list, as well. It’s not as agile as the Supra but it’s quick, fun and sounds better to my ears. 

A lot of your extra money turns up under the bonnet. These days the 440i packs BMW's slick B58 turbo straight six and the B4S does likewise. The boys from Buchloe in Bavaria (there are certain to be women there, too, I just liked the alliteration) added a pair of Alpina-spec turbos to generate a whopping 324kW and, more importantly, 660Nm. Alpina says 600Nm (the max torque figure of the brilliant M4 CS) is available from 2000-5000rpm, while the full 660Nm is available from 3000 to 4500rpm.

The M4 Pure has 317kW and 550Nm from the S55 straight-six. Just so you know.

Like the 440i but unlike the M4, the B4S employs the dependably brilliant eight-speed ZF automatic found throughout the BMW range.

You’re looking at a Supra that could be the peak of its model evolution because since the generation’s arrival in 2019 Toyota has increased the power of the 3.0-litre turbo-petrol in-line six-cylinder from 250kW to 285kW (torque remains the same at 500Nm) and introduced a six-speed manual. 

This 3.0-litre six-cylinder turbo-petrol is the only engine you can have with the Supra, there are no four cylinders or V8s - now there’s an idea. 

Toyota says the 0-100km/h time for the GR Supra with the manual gearbox is 4.4 seconds and 4.1 seconds for the automatic which comes with a ‘launch control’ feature.

Of course, all Supras are rear-wheel drive.

Alpina quotes 7.9L/100km on the combined cycle and we went through the premium unleaded at the rate of 11.7L/100km. I enjoyed myself, so that's not a terrible result.

Toyota says the 3.0-litre six-cylinder straight-six turbo-petrol engine in the Supra GT paired with the six speed manual gearbox should use 8.9L/100km after a combination of open and urban roads.

I did a week’s worth of city commuting and then a couple of hundred kilometres on country roads, but no motorways and the trip computer told me I was averaging 10.3L/100km.

Not bad for a big engine in a car tuned for performance, driven by a big kid who feels like he’s playing with somebody else’s toys.  

Premium 95 RON fuel is recommended, although 'standard' 91 is acceptable. A 52-litre fuel tank translates to a theoretical range of around 580km, dropping to approximately 500km using our real-world number.

One of the key differences between the B4 and M4 is the ride. While the M4 can crash over bumps and generally be a little hard to live with, the crew in Buchloe have gone after a much more plush ride. And in that they have succeeded because the B4 S is a mighty fine cruiser. Bumps are dismissed with a haughty disdain, even Sport + silliness doesn't completely write-off ride quality.

Very impressive too, is the steering. While still not at Lotus Elise levels of feel (few cars are), the Alpina tweaks connect the your palms to the road with more clarity than what you'll find in the 440i or M4. Where the M4 particularly adds too much weight, the 440i is a bit more circumspect in that regard.

And then we come to the engine. The B58 six is a belter, better even than the N55 that preceded it. It's still a 3.0-litre straight six but is part of BMW's modular engine family that starts with a 1.5-litre triple in the Mini and 1 Series. The Alpina-spec turbos are noisier, the Akrapovic exhaust lighter and also noisier. It doesn't have the all-out crackle and pop of an Audi or Merc (perish the thought), but when you're on it, the B4 means business. The 660Nm of torque, available over a wide rev range, delivers a steel fist wrapped in a velvet glove and bubble wrap - the speed builds rapidly but smoothly. 

The approach to the chassis tune seems to be based on the driving talents of mere mortals on normal roads, which is kind of like the 440i. It's terrific fun to drive hard but it's very forgiving and patient. The great thing about it is that you wouldn't think twice about jumping in it for the long haul, so comfortable and quiet is the cabin. The M4 will leave it for dead on a winding road, but that's perfectly fine.

One irritant is the replacement of the admittedly cheap BMW gearshift paddles with weirdly non-tactile buttons. They're not particularly easy to use and, probably worse for a sporty car, unsatisfying. It's an odd detail with which to go off the reservation. Cheeringly, the eight-speed ZF is its usual perfect self, so you don't have to worry too much about manual mode or go old school and use the shifter.

Ah, but what about living daily with a manual? As a car enthusiast most of the cars I’ve owned have been manuals and I’ve rarely cursed them because I love to drive.

But there were times when they were a pain, such as in traffic, or in traffic on steep streets and in traffic in shopping centres. Did I mention in traffic, also?

But on the nice roads with bends and dips, hills and sweeping corners, hairpins and twisty parts in places without traffic, then all is forgiven. 

And so it goes with the manual version of the Supra. 

Making life easier in the Supra GT is a clutch pedal without much travel so you don’t feel as though you’re at the gym doing a one-sided leg press.

I found the shifts themselves, while short, to be less than smooth. At first, I thought that the clunky changes might have been because the gearbox hadn’t been run in yet, but the odometer was saying 7500km, so this could just be the nature of the gearbox and after a few days I became used to it.

The rev-matching feature of this gearbox is a nice touch, especially on those sporty drives when you change into a gear and you’re thrown straight back into the power band again.

Superb balance, great steering with a nose which points exactly where you want it to and that magnificently smooth turbo-petrol in-line six posting all its meaty grunt to the rear wheels just behind your shoulders makes for a sports car that’s fun, talented and quick.

Good brakes (348mm ventilated rotors with four piston calipers at the front and 330mm discs with single piston calipers at the rear) and grippy Michelin Pilot Supersport tyres (255/40 fr - 275/40 rr) complete a great package. 

A ride that’s still comfortable over bad Sydney roads and surprisingly good visibility made the Supra easy to live with in the city, from parking to school drop offs.

Yes, used it each day for the school run with my older child and the grocery shopping. 

The GR Supra GT has not been crash tested by ANCAP, but its BMW Z4 twin scored a maximum five stars when it was tested by the European equivalent Euro NCAP.

Still, the Supra has seven airbags, there’s AEB with pedestrian and cyclist detection, lane keeping assistance and blind spot warning, plus front and rear parking sensors. There are seven airbags on board.

There’s no spare wheel, but there is a tyre inflation kit which should get you out of trouble.

Alpina offers a two-year/unlimited-kilometre warranty which is a bit behind the times and not in keeping with the price point. Servicing is another matter altogether and you're subject to your dealer's standard charges for servicing.

Toyota covers the GR Supra GT with its five-year, unlimited kilometre warranty. Servicing is required every 12 months or 15,000km and is capped at $415 per service.

The warranty is the industry standard in terms of time and kilometre length, and the capped service prices are very reasonable - a lot more affordable than a car with a prestige badge on the bonnet, too.
