A part from the looks, the highlight is the 310kW (415 hp) S55 3.0L inline 6 engine. This would have the next M3 and M4 featuring similar horsepower figures to the current M3 (414 hp) from the 3.0L inline 6 multi-turbo S55 engine. But, strong rumor has it the cars will boast approximately 100 lb-ft more torque (in range of 395 lb-ft)
The same strong rumours say that engineers were targeting E46 M3 weight. The E46 M3’s curb weight is 3,415 lb, while the current E90 M3 and E92 M3 weigh 3,726 and 3,704 pounds, respectively. This would represent an approximate 300 pound weight reduction; great news for BMW enthusiasts who bemoan the increasing weight of cars in general. The caveat to keep in mind however, is that curb weight is calculated based on the total weight of a vehicle with standard equipment, and with the ever growing list of standard equipment and technology in late model cars, don’t be surprised or disappointed if you don’t see exactly 300 pounds shaved. What’s important is that the E46 M3 weight is being used as a target, which in any scenario, should result in significant weight reduction for the new M3 and M4
With the latest F82 M4 prototype sighting (gallery below), we have seen the following:
• Double slatted kidney grilles
• M4 badge on kidney grilles (a la M6) (currently covered)
• LED headlights
• LED tail lights
• Carbon ceramic brakes (optional) being tested in signature gold color (just as on F80 M3 prototype)
• Hood power dome/bulge
• Sculpted double-bubble carbon fiber roof (like M6 Coupe)
• Production side mirrors (still under camouflage)
• Integrated trunk spoiler
• Wide fenders
• Slanted exhaust tips
• Production sideskirts
• Wearing Continental ContiSportContact tires – 275/35 rear (like F80 M3)
