GerGerman car specialist Alpina has increased the performance of their Alpina B5 BiTurbo and Alpina B6 BiTurbo with a total of 33hp and 30Nm.
Alpina did not share any press release with us regarding these facts. At Driving-Fun.com, we spotted the information and we compared the figures on the website of the Germans with our previous posts. In the main text of both vehicles 540hp is mentioned as the total amount of horsepower. This is 33hp higher than the Alpina B5 BiTurbo we drove last year. The maximum torque went from 700Nm to 730Nm.
The V8 engine fitted with two Honeywell-Garrett turbochargers produces 540hp at a moderate 5,200rpm and a maximum torque of 730Nm is available from 2,800 to 4,500rpm. Sprints from standstill to 100km/h are now done in just 4.5 seconds (0.2 seconds faster), the top speed is reached at 319km/h (+12km/h). The Alpina B6 BiTurbo goes from zero to 100km/h in 4.3 seconds and has a top speed of 320km/h.
Just as a comparison, the BMW F10M M5 is powered by the 4.4 liter V8 engine with M TwinPower Turbo package, which offers 560hp and 680Nm of torque. The new 2012 F10 M5 can accelerate from 0-100km/h in just 4.4 seconds, and 0-200km/h in only 13 seconds. The voluntarily limited top speed is 250km/h.
Stay tuned for our first encounter with the upgraded Alpina B5 BiTurbo at the Geneva Motor Show 2012.
