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.
Only by that time the japanese car specs might already be 5 years ahead...again
