BMW Alpina B4 vs Lexus LM 500H

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 Lexus LM 500h is luxurious, comfortable, practical, easy to drive and expensive. While it may appear to be the ultimate family car, with only four seats it's limited in terms of how many kids and their friends you can carry. On top of that, the privacy screen introduces accessibility issues to the kids you wouldn't encounter on other vehicles. If you are thinking of a Lexus people mover as your next family car I'd suggest looking at the LM 350h which has seven seats and no privacy screen. If you’re looking at a business class executive van the LM 500h would be perfect. 

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.

The LM 500h doesn't look real. More like a concept vehicle with its vertical face wearing that enormous grille. Feels like if you watched it for long enough you’d catch it transforming into some kind of robot. Yet, at the same time its styling is elegant and prestigious.

I have a confession to make. I used this Lexus as my office. Its interior is that comfortable and spacious. I'm also a parent and there were times where it was the quietest place to get some work done.

It also let me observe people's reactions as they walked past with their dogs not knowing what was going on inside behind those tinted windows. The people that noticed were clearly car enthusiasts as they knew what they were looking at and couldn't pass without gaping it awe.

The LM 500h’s interior is superbly plush with thick carpets, beautiful copper metallic trim and nappa leather seats.

As I’ve said, the cockpit up front is less luxurious than the extravagant first class section in the back behind that dividing wall.

And yes, I’ve seen large screens before but nothing that stretches the width of the vehicle.

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.

You might be able to take Lexus out of Toyota but it's very hard to take Toyota out of Lexus and this particularly applies to the practicality of the LM 500h.

Every day I discovered new compartments, tray tables and storage areas. There are so many cabinets, lockers and hidey holes that we almost left my belongings (an entire family of plushie toy capybaras) behind because there are so many places to check.

Of course, I'm talking about the rear compartment here because up front there's not much storage. In fact, it proved to be quite a problem in that I had nowhere to put my bag with somebody sitting next to me and no area behind the front seats to stow it, either.

Talking of seats, the LM 500h only has four of them, with two up front and two in the rear. Up front, the seats are supportive and large, but the rear seats - those are, well... have a look at the images.

We’re talking two large captain's chairs that look as though they’ve been removed from the first class section of a plane.

And while this might be suitable for businesses shuttling a couple of executives to and from meetings, for a family, even with two children, the extra couple of seats a third row offers would come in handy.

The LM 350h has seven seats over three rows and no privacy screen. A far better choice for families.

For device charging there are USB ports up front and in the rear. There are wireless phone chargers for those in the back seats but not up front.

The LM 500h has a cargo capacity of 752 litres with all seats in place.

The Lexus LM 500h sits at the top of its range and is without a doubt one of the most expensive people movers on Earth with its list price of $220,888.

As you would imagine the standard features list is as extensive as it is extravagant.

For starters, while the regular LM 350h has two rows of seating in the rear (seven seats all up, including the front two), the 500h has the third row removed and just two super luxurious and enormous fully reclining seats fill the entire space. It’s like a theatre back there.

That theatre theme keeps going with a media screen in the back so large it stretches the width of the vehicle. Seriously, it's a 48-inch screen to watch movies or connect to your device.

The sound system is probably the best I’ve experienced - a spine tinglingly incredible 23-speaker Mark Levinson set-up.

What else can I tell you? Those rear seats are upholstered in beautifully soft semi-aniline leather. They’re heated and ventilated with a massaging function and... ridiculously comfortable.

There’s four-zone climate control, windows which have an electronic shade that turns the glass opaque, there are wireless phone chargers in the doors and carpet throughout so thick you sink down into it as you step inside.

Our LM 500h was upholstered in the 'Solis White' leather which also brings contrasting and mesmerising copper metallic trim.

Oh, and there’s a wall with an electric glass screen that can be raised or lowered to separate the rear passengers from the driver.

I should have mentioned this earlier. The kids loved it, but these parents spent a lot of time telling the 10- and three-year old not to put the screen up again.

The rear occupants, aka the kids, can also lock the screen in place. Which they did, and so sound proof is the dividing wall that we can only just hear their uproarious laughter.

Up front, the cockpit is comfortable but it’s clear all the space and luxury is for those being driven around.

Still, the front seats are leather with heating and ventilation, there’s a 14-inch media screen and 12.4-inch digital instrument cluster, plus a head-up display. Sat nav, Apple CarPlay and Android Auto are also standard.

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.

The LM 500h is a petrol-electric hybrid with a 2.4-litre four-cylinder turbo-petrol engine which makes 202kW/460Nm and works in concert with two electric motors.

The front motor makes 64kW/292Nm and the rear makes 76kW/169Nm. The combined maximum power output of the two motors and the petrol engine is 273kW.

The LM 500h is all wheel-drive and has a six-speed automatic transmission.

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.

Lexus says after a combination of urban and open roads the LM 500h should use 6.6L/100km. In our own testing we found consumption was higher at 9.4L/100km.

Worth noting my driving environment was mainly a hilly suburban one filled with school drop offs. Achieved some personal bests this week, with one long run to Sydney’s outskirts, only to return in nightmarish peak hour traffic.

Premium (95 RON) fuel is required and the tank size is 60 litres. In theory the driving range is a smidge more than 900km, which drops to around 640km using our real-world average.

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.

Quite simply, driving the LM 500h is like piloting a limousine on stilts. Superbly comfortable, but with an elevated driving position that offers outstanding forward and side visibility, the LM 500h is an easy vehicle to drive for long periods of time.

A digital rear vision mirror means visibility behind is good and unobstructed by the privacy screen or the seats.

The drawbacks are down to the lack of space up front, with the driver’s chair limited in its ability to recline or slide back due to the bulkhead behind it.

And that's compounded by the lack of cabin storage for bags if the front passenger seat is taken.

As for the rear passengers there aren't many people movers offering this level of comfort, except perhaps the Zeekr 009.

Variable suspension that adjusts continuously keeps the vehicle composed and provides a high level of comfort for those in the rear. At the same time, the LM stays nice and flat through roundabouts while remaining civilised over speed bumps.

And then there's the acceleration, which, while not supercar-like is incredibly brisk for a van. The all-wheel drive system provides outstanding traction in wet and slippery conditions, too. 

Our family used the LM daily for everything from school runs to shopping trips and weekends away and not only was it fun to drive, our lucky rear passengers enjoyed sitting high and being able to see clearly out their windows along with the luxury of a giant movie screen.

The Lexus  LM 500h is yet to be tested by ANCAP so it doesn't have a safety assessment score. There is, however, a high level of safety tech onboard including AEB which can detect pedestrians, cyclists, motorcyclists and other vehicles, emergency steering assist, lane keeping assistance, road sign recognition, rear cross-traffic alert, front and rear parking sensors as well as six airbags.

For child seats there are ISOFIX points and top tether anchor mounts on the two rear seats. We have a forward facing child seat and found it easy to install.

A space-saver spare wheel is located under the boot floor.

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.

Lexus covers the LM 500h with a five-year, unlimited kilometre warranty. 

The Lexus Encore Platinum program is complimentary for LM owners for three years, providing 24-hour roadside assist, a loan vehicle or pick-up/return service at service time, 'On Demand' vehicle evaluation options, valet and airport parking benefits as well as exclusive offers and event opportunities.

Servicing is recommended annually or every 15,000 kilometres, and impressively, pricing is capped at $695 per service over five years.
