This is the closest thing you can buy a to a BMW M7

If a garish performance version of the luxury BMW 7 Series appeals, you’re in luck. While BMW has yet to give into pressure to make an M7, Alpina has other ideas.

The B7 super saloon will make its debut at next month’s Geneva Motor Show – but these official pictures of the American version have been revealed.

The biggest difference with the American version over the European car is the four-wheel-drive system. Ours will be rear-wheel drive, adding a few tenths to the claimed 3.6-second 0-62mph time of the US-spec B7.

That makes it 0.8 seconds quicker than its predecessor, while a 193mph top speed has been mooted. This impressive performance comes from a twin-turbo 4.4-litre V8 producing 608hp, with 494lb ft of torque available from just 2,000rpm.

A bespoke stainless steel exhaust system is fitted with active exhaust valves that can be opened or closed by the driver by switching the Driving Dynamic Control switch between Comfort and Sport mode.

This also tweaks the air suspension which, the firm says, “retains the exceptional long-distance cruising comfort of the predecessor while at the same time significantly sharpening the agility, handling and lateral dynamics.”

For the first time, the B7 will feature rear-wheel steering, while a Sport+ mode within the suspension settings decreases ride height by 20mm and increases front camber for even more direct turning. Have no doubt, this will be the best handling 7 Series yet.

In typical Alpina fashion, the external tweaks are minimal – lightweight 21-inch alloys look the business, while exclusive blue and green paint colours finish it off.

Inside, the B7 features Nappa leather, ceramic inserts on ‘selected control elements’ and soft-close doors. A full-colour head-up display and rear-view camera are both standard on the US model, but European specifications are yet to be confirmed.
