BMW Alpina B10 V8S 4.8 (E39) Dyno

BMW ALPINA

The B10 V8 was the one of most successful cars in Alpina’s history, with over 1300 cars sold since it’s launch in March 1997. However, over time more and more powerful sport- saloons entered the market and 347 bhp simply wasn’t enough. So for the last model- year of the E39, Alpina introduced the B10 V8S at Geneva auto-show. The ‘S’- designation refers to classic models such as the limited E12 B7S Turbo. The B10 V8S is not as rare as its older brother but it is still quite a special car.
Engine/ Gearbox
The V8S uses a modified version of B10 V8 engine. The bore is exactly the same at 93mm but the new crankshaft has increased the stroke from 85mm to 89mm which increases the displacement 4837cm3. Others changes include a reworked and improved intake system and new piston-rings. At 5800 rpm the B10 V8S develops 375 bhp and 510 NM of torque at 3800 rpm. The gearbox is the same 5-speed automatic with Switch-Tronic as the standards B10 V8. This same engine was later used in the Z8-based Roadster V8 and even became a BMW production engine in the X5 4.8 is.
Suspension/ Brakes/ Wheels
The suspension has a stiffer set-up than the standard B10 has, but not by much. Alpina have designated the suspension to work with the beautiful 19” wheels the B10 V8S is equipped with. The front wheels are 8.5” wide and has 245/35 tires while the rears are 9.5” wide with 275/30 tires. However the 18” wheels from B10 V8 are still available as no-cost option. Behind the front wheels the much improved brakes can be found. The 360X34mm discs are drilled and 4-piston calipers, which are made of aluminium by Brembo, are finished in blue with silver Alpina logo.
Interior/ Exterior
The B10 V8S is very subtle. The exterior changes include a front- spoiler, identical to the B10 V8, a new rear- spoiler, the 19” wheels and the exhaust-pipes. Inside, it has the classic Alpina- designed anthracite cloth, a hand- stitched steering wheel in Alpina-design, blue instruments with red needles, Alpina door-sills and velour floor mats and Ruster Maser wood-interior. The stripes are a no-cost option and available in silver or gold and of course it has a silver-plated production plaque. If the money is not object there are some interesting options such as Alpinablue or Alpinagreen paint, the very nice velour-mat for the luggage compartment in Alpina design, the B10 V8S-sign on the B-pillar and Lavalina leather interior
