BMW Alpina B5 vs Hyundai Genesis

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 Genesis is not quite a match for cars twice its price but it makes you think what's possible. It doesn't have the dynamic brilliance of a BMW or the self-assured faultless execution of a Mercedes. Lexus ought to be worried, though - why would you have an LS when you could have this? The only answer is 'badge'.

The Genesis is an epoch-making car for the Korean manufacturer. As the company has got better, there are fewer excuses for overlooking it. While the Genesis is pitched into a shrinking market, it's not really meant for the average i30 buyer to buy, but to see.

It's bristling with tech and is not only a halo car but a shot across the bows of both Lexus and the Germans. Attached to that shot is a note: "We're coming for you." In other words, Hyundai got it right.

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 Genesis is like no other Hyundai. For a start, it's gigantic - it looks easily as big as a BMW 7 Series (it isn't) with the road presence to match. There's a lot of BMW from most directions, but with a sharper approach to the creasing and character of the sheet metal.

Towards the rear it's more BMW 6 Series Gran Coupe and is all the better for it. The style is understated and technocratic.

Inside is also very Germanic, but with a bit more of a Lexus feel

The big wheels from the Ultimate pack help make it look lower and sleeker, too.

Inside is also very Germanic, but with a bit more of a Lexus feel. Our car had the lighter leather which meant that the wood and the metal materials didn't necessarily work well together.

The interior is expertly put together and feels like it will last forever.

The only jarring moment is the gear selector is shared with our long-term Hyundai i30 - it looked a bit cheap in what is otherwise a beautifully executed cabin - it needs more heft.

On Australian-delivered cars there is just one Hyundai badge, sitting proudly on the boot - you get the feeling this was debated long and hard and when the decision was made to go for it, a big one was chosen.

However, the winged Genesis branding takes pride of place everywhere else. When you approach the car at night and the puddle lamps come on, the Genesis logo is projected on to the ground, crisp and clear.

The only way to describe the Genesis' pricing is aggressive - kicking off at $60,000, it's the most expensive Hyundai money can buy, but with a spec list like this, you won't feel at all short-changed.

Your sixty large buys you a huge cabin with a seventeen speaker stereo, auto headlights and wipers, LED ambient lighting inside and out, dual-zone climate control, keyless entry and start, powered front seats which are heated and cooled, satnav, front and rear parking sensors, and plenty of other bits and pieces.

Our car had the $22,000 Ultimate package, adding 19-inch alloys, blind spot sensor, front and side cameras, around-view display, real leather, more adjustments for the driver's seat, ventilated seats in the front, heated rear seats, panoramic glass sunroof, acoustic glass, heads-up display, powered bootlid and LED foglamps.

The Genesis is like no other Hyundai

You can have a lot of the more useful features in the $11,000 Sensory Pack. It's a good middle ground that, for example, features the excellent heads-up display.

The 9.2-inch screen splits the asymmetric air-conditioning vents. The software is unique to the Genesis and a huge leap forward over the rest of the Hyundai range - classy, smooth graphics, a good responsive screen.

You control the seventeen speaker stereo from here, which kicks out a rich sound and an impressive Bluetooth performance - rear seat passengers can also run the stereo from their armrest. The satnav is detailed and chatty, while the excellent heads-up display shows a configurable information set in strong, clear graphics.

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 Genesis is powered by Hyundai's own 3.8-litre V6 developing 232kW and 397Nm, mated to Hyundai's eight-speed automatic transmission.

Despite weighing just under two tonnes, the Genesis completes the dash to 100km/h in 6.5 seconds.

It has a claimed 11.2L/100km on the combined cycle. In what must be a first, we got below that, averaging 10.8L/100km over two weeks. And that's without stop-start fuel-saving to blunt the effect of lot of city driving.

The Genesis is not going to tempt you into a track day, even with rear wheel drive

We'd still like to try the V8 - only available in left-hand drive markets - though.

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.

At five metres long, with a ride firmly pitched in the luxury camp, the Genesis is not going to tempt you into a track day, even with rear wheel drive.

Blindfold your passengers and swap them between a Lexus, a BMW and a Genesis and the overwhelming impression they'll get is one of incredible smoothness.

If you're wanting sudden movements, this isn't the car for you

Sitting in the back of the Genesis, it's easily as good as the German and luxury Japanese competition. The seats are hugely comfortable, there's ample head, leg and shoulder room and it feels lot nicer than anything within a bull's roar of its price.

No matter where you sit, it's an incredibly quiet car. The engine is a distant whoosh, the tyre noise muted and there's almost no wind or ambient noise. It's supremely comfortable and the excellent stereo will wash away what little noise does invade.

It certainly feels its weight from the driver's seat, with a competent, soft turn-in, but if you're wanting sudden movements, this isn't the car for you.

The Genesis is an epoch-making car for the Korean manufacturer

On fast flowing roads you can have some fun, but things will get floaty and that will quickly kill that fun. The ride and isolation from the rest of the world is completely worth it.

Nine airbags, traction and stability control, lane departure warning, forward collision control, ABS, brake force assist and distribution and traction and stability control bring the ANCAP count to five stars.

The Sensory and Ultimate packs add blind spot sensors and around view cameras.
