The new Alpina XD3 Biturbo will arrive with British customers in April, bearing a starting price of £57,900.
Based on the BMW X3, the German SUV will use a 3.0-litre twin-turbo straight six diesel engine that produces 329bhp and 700Nm of torque.
Sending its power to the wheels via an eight-speed automatic gearbox, it allows for a 0-62mph sprint of 4.8 seconds. That puts the newcomer on a par with the Bentley Bentayga Diesel and Audi SQ7 – the fastest-accelerating diesel 4x4s in the world.
To achieve this performance, Alpina’s engineers have applied an obsessive attention to detail. There’s a clever cooling system that continuously manages engine temperatures and a lightweight exhaust. The company has even made the brakes lighter.
Other tweaks include a modified four-wheel-drive system with a limited-slip differential. The new set-up allows up to 90 percent of the engine’s power to reach the rear wheels.
However, Alpina GB’s brand manager, Gary Lott, says the XD3 is about more than just the performance figures.
“Our cars are for driving enthusiasts who value a blend of qualities that can only be delivered by immense attention to detail,” he said. “The XD3 is built with just one powertrain and two chassis specifications, which allows our engineers to calibrate every component and every control system to work perfectly together without compromise.
“Alpina’s dynamics specialists have spent months optimising the chassis not by hurling it around a race track, but by simply driving as customers would: on roads, enjoying every mile however fast or slow. The result is remarkable ride quality combined with a pin sharp driving experience.”
Key in this mission, the company says, is the new suspension set-up. Shorter, stiffer springs have been fitted to reduce the body roll in corners, while “selectable” dampers have also been fitted. Offering the driver a choice of modes, these dampers allow the car to be tuned for sporty driving or long-distance cruising.
The list of standard equipment is long, but highlights include a 10.25-inch digital instrument cluster, satellite navigation and leather upholstery. Trademark Alpina features, such as the 22-inch multi-spoke alloy wheels and sports steering wheel also star.
As with all Alpinas, the vehicle has been built with BMW’s blessing, and a three-year/124,000-mile BMW-endorsed warranty is included.
