BMW Alpina B5 vs Lexus LM 500H

What's the difference?

The Alpina B5 is a special car – more special than most people will ever give you credit for if you own one. Those that do know what an Alpina is will let you know; people will cross dangerously busy streets to talk to you about your car. Insanely fast, almost incomprehensibly comfortable and effortlessly powerful to drive.

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. 

Interesting is the right word for it, because while it might be questionable that Alpina's changes to the exterior are aesthetic pleasing, they are definitely intriguing to those who aren't familiar with the brand.

First, there are those 20-spoke wheels. Alpinas have worn this style of wheel forever and they've become the most famous outward sign that this is not just another BMW. So don't under any circumstances take them off and replace them with anything else. You'd be run out of town by the Alpina mafia.

Yes, they're more painful to clean than a cheese grater (trust me, I know. And if you look closely at these images you can see the dirty bits I've missed), but if you really don't like them then perhaps it's a sign this car isn't for you.

Then there's the boot-lid spoiler. It's square and 1980s'-looking, it also appears a bit like it's been bought online and installed by a teenager, but again, this is another Alpina tradition and it suits the car's character perfectly.

All right, those pinstripes; they're known as the Deco-Set and are a hat-tip to the Alpina racecars of the 1970s and '80s. Again, don't take these off, your Alpina will drop through the centre of the Earth in value. These are also part-and-parcel of owning one of these cars. I'm not a massive fan of them.

But I'm all about that front spoiler, with the floating Alpina lettering that you can option in silver, high-gloss black or gold.

Inside, there are fewer Alpina additions, but they're nonetheless unmissable. There's the Alpina-badged steering wheel, and a new virtual instrument cluster, embossed headrests and  illuminated door sills.

There's also the little numbered plaque on the centre console which proves its authenticity, ours was number 49. Out of how many? I don't know. But I do know Alpina produces only about 1700 cars globally a year. Rolls Royce does about 4000. So, you can rest assured your B5 is exclusive.

At almost 5m long, 1.9m wide and 1.5m tall, the B5 is a large saloon, but having recently reviewed the Alpina B7 it feels small in comparison. How does it drive? We're getting there.

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.

Practicality is not really a BMW strong point no matter which model you pick. See, BMW mostly makes the car equivalent of uber-stylish and skin-tight active wear which looks good and performs brilliantly, but sometimes you just want pockets and a bit of room for your… um… bits and pieces.

So while there are two cup holders up front and two in the back, the bottle holders in the doors aren't huge, the centre console bin is on the small side, there's a hidy-hole in front of the shifter, the glove box is just a box for little more than gloves and there's no other great cabin storage options.

Legroom in the rear is good but not great, too - I'm 191cm tall and have about 30mm between my knees and the seat back in my driving position. Middle-seat passengers will also have to straddle the drive shaft hump in the floor. Headroom is restricted in the back, too (you could blame the sunroof) with my hair just skimming the headlining (I do have big hair).

Under that power tailgate, the B5's boot capacity is 530 litres which is 15L more than its big sister, the B7. There are two plastic storage areas either side of the luggage space for wet things. While there is one USB outlet in the front there aren't any in the rear.

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.

The Alpina B5 uses the same 4.4-litre V8 engine found in the BMW M5 (and also the B7). But, and it's a big but, the M5 makes 441kW and 750Nm, while the B5 outdoes it with 447kW and 800Nm. Admittedly, the B5's torque arrives at the 3000rpm mark, while the M5's is all there from 1800rpm.

How does the B5 beat it? Alpina installed its specially developed twin turbochargers and intercoolers, a high-performance cooling system, a reconfigured air intake set up and a different exhaust system.

The B5, though, is a tenth of a second slower to 100km/h compared to the M5 with a time of 3.5 seconds, but it will blast on to a top speed of 330km/h while the M5 is limited to 250km/h in regular form and 305km/h with the optional M Driver's package.

Both uses the same ZF eight-speed automatic transmission with identical gear ratios, and both are all-wheel drive.

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.

The Alpina B5 needs petrol. By that, I mean it needs quite a lot of it if you want to enjoy it properly. What type of mileage does it get? Officially, it should use 11.1L/100km after a combination of urban and open roads, where as the M5 is set to 10.5L/100km.

That makes sense, the B5 produces more power and torque, and it's 85kg heavier than the M5 at 2015kg.

Our test car's trip computer was reporting 13.2L/100km after flying low over country roads and slow city piloting. The more time spent in the urban warfare that is the daily peak hour commute, the more that figure crept and hovered around the 15L/100km mark.

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.

Ok, stay with me here. For this next bit you'll need a fresh egg, a lounge chair, and it might be a good idea to have some plastic bags and carpet cleaner on hand.

First, in front of the lounge chair flatten out the plastic bag and place the egg on it. Next, sit down on the chair and very carefully rest the ball of your foot on the egg with as little pressure as humanly possible.

This is exactly how little force you need to apply to the go-pedal of the B5 to accelerate from a standstill to 60km/h in about five seconds.

If anything sums up the driving experience of the B5, it's that sense of effortlessness.

Stomp on that accelerator, and you'll be shot to 100km/h in 3.5 seconds, without a hint of broken traction thanks to the all-wheel-drive system.

The ride should have been terrible on 20-inch wheels shod in low-profile rubber (Pirelli P Zero 255/35 front, and 295/30 rear), but the Alpina-tuned air suspension is close to miraculous in the way it cushioned and censored the potholes out of Sydney's worst roads. Yes, it can be a touch floaty, particularly in the Comfort Plus setting, but this is benchmark-setting stuff for a comfortable ride.

Don't expect this beast to roar. Unlike the M5, the B5 gets its work done without deafening everybody around it. Sure, the B5's V8 sounds amazing when you push it, but it's not brash, not loud and not lairy. Buy an M5 or Mercedes-AMG E63s if you want to be heard half a block before you get home, but you won't get that with the B5 and its exhaust system.

The B5 also handles well, but I have to say the engagement factor is low. I piloted it effortlessly through the twists and turns of my country test circuit and roads which normally have me grinning like a maniac behind the wheel had me feeling a bit disconnected in the B5. That air suspension, the numb steering and pedal actions make it difficult to ‘feel' the road.

It's highways where the B5 is a king, but even at 110km/h there's the sense that this car is still fast asleep and won't get out of bed for anything less than 150km/h - making it perfect for Germany's autobahns, but maybe not for here in Australia.

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.

The Alpina B5 is covered by BMW's three-year/unlimited kilometre warranty. Servicing is recommended every 12 months or 15,000km.

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.
