Most of these are already posted but here it goes, the Official info:
* First eight-cylinder for the BMW M3.
* 420 hp from 4.0 litres.
* Maximum torque of 400 Newton-metres (295 lb-ft) at 3, 900 rpm,
85 per cent of maximum torque over a speed range of 6,500 rpm.
* 340 Newton-metres or 251 lb-ft available from just 2,000 rpm.
* Maximum engine speed 8,300 rpm.
* Consistent lightweight construction of engine and ancillary units,
new V8 power unit one of the lightest eight-cylinders in the world,
lighter than the straight-six power unit in the former model.
* Variable camshaft control, low-pressure double-VANOS for an
optimum charge cycle, system offering full power and performance even with normal engine oil pressure.
* Eight individual throttle butterflies for spontaneous engine response.
* Consistent and reliable oil supply with longitudinal and lateral acceleration up to 1.4 g ensured by two oil pumps and wet sump oil lubrication.
* Exhaust system optimizing cylinder charge, optimized for weight and function by means of internal high-pressure remoulding, exhaust emissions fulfil EU4 and LEV 2 standards.
* Upgraded MSS60 engine control unit for optimum coordination of all engine functions with the various control systems in the car.
* Ion flow technology recognising and distinguishing engine knocking phenomena as well as misfiring and miscombustion by measurement of ion flow in the combustion chambers.
* Brake Energy Regeneration with intelligent alternator control.

Double row roller chains with not one, but two sprockets permanently machined on the crank. Gear drive between the intake and exhaust. Variable cam timing for both intake and exhaust. They are definitely convinced there won't be problems with cam drive.

When you're comparing cars like the IS-F and M3, the rims aren't there "just for the look".
From a rough glance, the IS-F's wheel/tire setup looks slightly more aggressive than the M3's.
We're not talking about 30" tires here, or SUVs/trucks. The world's best sportscars have bigger than usual wheels. You don't see McLarens with 16" wheels.
I find it interesting that the M3 Concept has 19" tires, yet the production car will only have 18" standard. 19" wheels will be optional. BMW sure loves to make everything an option.
