A few weeks after teasing the new 2018 BMW Alpina D5 S high-performance diesel-powered car, Alpina is now letting more information out of the bag. This new creation based on the BMW 5-Series that’s tagged as the fastest serial diesel car in the world comes in two body types – saloon (sedan) and touring (estate or wagon).
Alpina is introducing the new BMW Alpina D5 S to the global audience at the 2017 Frankfurt Auto Show. Expected to be the highlight of the Buchloer booth, the Alpina D5 S is eager to prove its worth as a diesel car that could give petrol-powered sedans and wagons a run for their money in terms of acceleration and speed.
The new BMW Alpina D5 S is derived from the new G30 generation of the BMW 5-Series. The BMW Alpina D5 S may have less power output as BMW’s high-performance M550d, but it has more torque. This allowed the BMW Alpina D5 S to be as quick as the BMW M550d. However, electronic limitations were loosened up a little, allowing the D5 S to be faster than the M550d.
According to Alpina’s Web site, the new D5 S is powered by a 3.0-liter straight-six diesel engine fitted with three turbochargers and common rail high-pressure direct injection, delivering 285 kW (388 hp) of max output between 4,000 rpm and 5,000 rpm as well as 800 Nm (590 lb.-ft) of peak torque available between 1,750 rpm and 2,650 rpm. This compared to 400 hp of max output and 670 Nm of peak torque delivered by the B57 quad-turbo diesel engine in the M550d.
This insane amount of power is sent to all four wheels (all-wheel drive system) through the latest generation of the eight-speed Sport Automatic Transmission with Alpina Switch-Tronic, which is derived from the ZF 8-Speed automatic gearbox. This gearbox offers three modes – Automatic, Sport and Manual (through buttons on the back of the steering wheel).
Both the saloon and the touring versions of the D5 S are as quick as their M550d counterparts in the 0-100 km/h sprint. The saloon version of the BMW Alpina D5 S could dash from nil to 100 km/h in 4.4 seconds, while the touring variant could do the same in 4.6 seconds. However, while the M550d (both versions) has an electronically limited top speed of 275 km/h (155 mph), the D5 S could go faster. In fact, according to Alpina, the saloon version has a top speed of 286 km/h, while the touring model is a bit slower at 283 km/h.
To complement this power and to effectively make the D5 S a high-performance machine, Alpina made a number of changes on the chassis and suspension. For instance, the suspension system of the BMW Alpina D5 S makes use of electronically controlled dampers as well as shorter and stiffer springs, with the touring version employing a rear-axle air suspension. An ALPINA Sport Plus suspension package is offered as optional for the new D5 S. The D5 S rides on new Alpina Classic 20-inch forged wheels as wrapped in Pirelli Ultra-High-Performance tires -- 255/35 ZR20 at the front and 295/30 ZR20 (Touring: 285/30 ZR20) at the rear.
Braking power comes in the form of the system found in the BMW Alpina B5 Bi-Turbo. This braking system includes four-piston fixed brake calipers with 395 mm discs on the front, as well as floating brake calipers with 398 mm discs and an electromechanical parking brake on the rear. An optional brake system with light-weight drilled composite discs and high performance is also available.
In Alpina’s typical fashion, the exterior tweaks were quite discreet. These include the Alpina wheels, Alpina splitters and stickers, an additional opening in the front apron, new Alpina lettering in the front spoiler as well as the Alpina Deco-Set and sporty exhaust system. These also include two exclusive Alpina paint finishes: Alpina Blue metallic and Alpina Green metallic.
Inside, the new BMW Alpina D5 S features a hand-crafted Alpina sports steering wheel made from Lavalina leather with blue/green stitching, illuminated door sills, model designations as well as an individual production plaque. The interior also features a full-color LED digital instrument panel with distinctive Alpina design. The interior could be availed in several trim options like Alpina Piano Lacquer, Alpina Luxury Wood Myrtle, and Alpina Luxury Wood Walnut Nature.
