New details on the powerful 2017 BMW Alpina B7 super saloon have been revealed ahead of next month's Geneva motor show.
The B7, based on the new 2016 BMW 7 Series, is driven by a 4.4-litre twin-turbocharged V8 petrol engine. Some markets will also gain BMW's xDrive all-wheel drive system, while others will go rear-wheel drive only.
The B7's engine, which is the same as the one currently in the Alpina B5, has a peak power output of 447 kW and 800 Nm of torque (available from 3000 rpm). All of this will be transmitted through an eight-speed sports automatic transmission with Alpina Switch-Tronic paddles mounted on the back of the steering wheel, developed in collaboration with ZF.
The power comes as a result of several tweaks under the bonnet. Development in the twin-scroll turbo-chargers will bring the boost up to 1.37bar (20psi), while an upgraded intercooler will handle the excess heat and new high-performance pistons are fitted to accommodate the increase in power and forced induction.
A new stainless steel exhaust is also on the job to up the aural delights, which can be regulated from within the cabin via the Driving Dynamic Control (DDC). The extra power from the bavarian barnstormer's V8 results in a claimed 0-100 km/h time of around 3.6 seconds. Slightly slower times can be expected on non-xDrive models, like those that are headed to the UK market.
The DDC system will also control the car’s chassis settings. The B7 will feature an adjustable air suspension system as well as adjustable dampers and Road Preview, that uses the onboard GPS to adjust the car’s suspension to suit upcoming corners.
The B7's active air suspension, along with the ability to carve upcoming corners, will also adjust to suit the speed at which you are travelling. If you're moving at speeds above 225km/h, the car will hunker down by two centimetres, helping to lower the centre of gravity and aid stability. On the other hand, when travelling around town with plenty of speed bumps and potholes, the car can raise itself by 2cm to avoid any scrapes that might otherwise occur.
Alpina classic 20-inch wheels are fitted as standard, though 21-inch wheels are an option. Braking will be carried out by 394mm front and 368mm rear discs and four-piston calipers all round. A long list of interior standard equipment comes with the new B7, including Nappa leather, comfort seats, a leather wrapped instrument panel, full-colour HUD and a digital LED instrument panel.
Changing between driving modes will also change the style of the HUD and instrument panel. Whilst in comfort mode, the panel will feature round instruments, a blue background and red needles. In sport mode, the design changes to blue and green drag indicators and focuses on primary information, such as the centrally positioned digital speed read out.
