New BMW ALPINA D4 Bi-Turbo Convertible, world’s fastest production diesel open top car, now available in UK

Elegant new high-performance Convertible combines 0-62 in 4.7 seconds with outstanding comfort, 47.9 mpg and CO2 emissions of just 156 g/km, slashing benefit in kind taxation

Sytner Nottingham (UK): Bespoke vehicle manufacturer ALPINA is building on the success of its extraordinary D3 and D4 Bi-Turbo models with the introduction of a new D4 Bi-Turbo Convertible. The folding hardtop equipped vehicle features the same twin-turbo diesel powertrain that pairs 350 hp and 700 Nm of torque with combined cycle fuel economy of 47.9 mpg and CO2 emissions of only 156 g/km. The result is a class-leading top speed of 171 mph, a 0-62 mph time of just 4.7 seconds and benefit in kind taxation that is unrivalled amongst cars offering equivalent performance, style and luxury.

“The headline figures make the D4 Bi-Turbo Convertible a remarkable engineering accomplishment, with a unique blend of performance, economy and taxation benefits for a four-seat open top vehicle,” says ALPINA GB Sales Manager Gary Lott. “ALPINA is synonymous with exquisite convertible cars, and the marriage of its high-output diesel powertrain to BMW’s folding hard top bodyshell provides the ultimate evolution of this theme for a marketplace where economy and emissions are now as important as performance and refinement.”

The D4 Bi-Turbo Convertible is based on BMW’s latest generation 4-Series, and is the result of a two year development programme: ALPINA analysed and refined every aspect of the car to increase performance, improve comfort, efficiency and aesthetics. Using design and validation processes identical to those implemented by BMW, ALPINA’s team of 70 development engineers worked with specialist suppliers to enhance the engine, gearbox, cooling system, body structure, wheels, tyres, aerodynamics, suspension and interior.

“The driving experience is of vital importance to our customers, and the sensation is magnified to visceral levels in any ALPINA open top car,” says Lott. “Acoustics are optimised through the use of a computer-controlled valve in the free-flowing exhaust. Making the most of a twin-turbo, aluminium straight-six soundtrack is a priority for ALPINA engineers, be it for petrol or diesel derivatives.”

Bespoke Luxury

Standard equipment includes an eight-speed automatic gearbox, Adaptive M Sport Suspension, leather upholstery, electrically adjustable heated sports seats, climate control and Bi-Xenon headlights. Inside, there are luxury carpet overmats and subtle ALPINA logos on the seat backs and door sills. The instruments are in ALPINA Blue and the steering wheel is covered in finest-quality, hand-stitched Lavalina leather.

Outside, the new D4 Bi-Turbo Convertible receives subtle aerodynamic enhancements developed in BMW’s wind tunnel, a four outlet exhaust with an ‘intelligent’ acoustic valve, and 19” ALPINA alloy wheels in the company’s famous Classic design. Every car is finished with a model plaque displayed on the centre console, showing the car’s unique build number.

Almost limitless personalisation from ALPINA’s craftsmen can be added to BMW options to provide a truly bespoke vehicle. Alongside the famous ALPINA Blue and ALPINA Green signature paintwork, choices include hand-stitched full leather interiors of superb quality and a wide range of hand-finished woods for the dashboard and doors. The Convertible can also be specified with an exclusive wind deflector complete with ALPINA imprint, and an Air Collar.

“Historically, ALPINA has been the connoisseur’s choice; a responsible way to indulge an interest in driving, an appreciation of fine engineering and the benefit of finely-honed attention to detail,” concludes Lott.

ALPINA has worked closely with BMW since 1961, with shared warranty coverage since 1964. The company was registered as an automobile manufacturer to ISO standards in 1983. The new ALPINA D4 Bi-Turbo Convertible is available in the UK from £54,950 with orders now being taken for spring delivery.
