BMW tuner to expand its offering to include fast 3 Series-based four-door coupe
Alpina has released a fresh tease of the B4 Gran Coupe it’s set to launch later this month that will be based on the latest-generation 4 Series.
Posting a single image of the B4 Gran Coupe it will unveil, the famed German tuner’s latest creation will feature a small lip spoiler and its trademark pin stripe decoration.
Set to be based on the 430ix variant of the G26-generation BMW 4 Series Gran Coupe, under the bonnet the fast B4 Gran Coupe will share the latest B3 sedan’s twin-turbocharged 3.0-litre inline six-cylinder and produce an identical 345kW and 700Nm of torque.
Those are 50Nm more torque than the current BMW M3 but 30kW less power.
It’s thought the Alpina B4 gran Coupe will only come with all-wheel drive and feature a tweaked version of its eight-speed automatic which is expected to have been beefed-up to cope with the extra torque. It will also offer quicker shifts and improved responses compared to the standard car.
Performance should be explosive for a small four-door. Expect the B4 to sprint from 0-100km/h in just 3.8 seconds and top out at around 305km/h.
It’s been tipped, once launched, a diesel-powered D4 Gran Coupe will be offered in some markets that will use a tuned twin-turbocharged 3.0-litre inline-six that will produce 261kW and 730Nm of torque and be able to blend a 4.6-second 0-100km/h with the ability to average 6.7L/100km.
Whether you choose petrol or diesel, the Alpina B4 will come with a bespoke suspension tune that will feature new springs and dampers that aim to offer more body control compared to a BMW M440i but greater levels of comfort beside a more extreme BMW M3.
The all-wheel drive calibration will have also been adjusted for greater agility, while the introduction of a new mechanical limited-slip differential should guarantee a rear-biased handling.
Featuring a traditionally subtle body kit, the Alpina will get unique badging, an upgraded interior and its trademark 19- or 20-inch Dynamic alloy wheels.
Following its March unveiling, the Alpina B4 Gran Coupe is expected to come to Australia and be priced around $150,000, matching the outgoing B4 S BiTurbo Coupe.
