Let's see how about... a 3.8-liter twin-turbocharged 24-valve V6;
485 horsepower @ 6,500 rpm and say...
434 lb-ft of torque @ 3,200–5,200 rpm
max 7500 rpm
Ultra low emission vehicle
Aluminum pistons and magnesium oil sump
Pressurized lubrication system
low back-pressure exhaust system
secondary air intake system to rapidly heat catalysts to peak cleaning efficiency
Rigid, lightweight carbon-composite main driveshaft
High-performance 1.5-way mechanical limited-slip rear differential
Dual clutch 6-speed transmission (but that one will be fully sorted out
)
Sounds good right ?
Tall order but BMW can do it.
And if they can't well they can still look up here for some help.
