Next BMW M5 to cut CO2 emissions by 20%, no hybrid ق Autoblog Green
To do that, BMW will follow an increasingly common path with direct injection, turbocharging and revised gearing. The M5 will apparently use a version of the 555 hp turbocharged 4.4-liter V8 from the X5M/X6M. The increase in torque from the 383 lb-ft at 6100rpm of the current 5.0-liter V10 to around 500 lb-ft at 1500rpm will allow BMW to use much taller gearing for lower engine rpms.
I know a company that's tired of paying extra taxes on their gas guzzlers!
I bet the used v10 models are gonna go for a pretty penny - what a motor!
On that note, i'm very glad CAFE is tightening up. Suddenly we have small turbo 4's in ordinary cars, direct injection, electric vehicles, and v8's are dissapearing.. hmmmmmm, funny coincidence.
