Another M vehicle is spied during a testing session at the famous Nurburgring. The 2013 F80 BMW M3 Sedan goes around the track for a new trial before its release next year. Initially introduced in a sedan form, the F80 M3 will be followed by the Coupe and Convertible variants, all using the same engine.

And this is where they mystery comes in plan. Previous reports were associating the new M3 with an inline-six engine while more recent ones point to a radical change in BMW M’s philosophy: a turbocharged V6.

Some of our sources says that the V6 is a 3.3 liter BiTurbo engine with around 450 horsepower, an information that has been denied by others, so at this point, any news around the new M3 engine are to be taken with a big grain of salt. To add even more fuel to the fire, Car and Driver has recently published their own opinion on the V6:

“The new V6 will be the first to mount its two twin-scroll turbochargers within the vee-angle, mirroring the company’s 4.4-liter V8 design. The This unique-to-BMW approach reduces the length of the inlet tract compared with a regular turbo-vee setup, helping to sharpen throttle response and minimizing heat buildup after air passes through the intercooler. A 60-degree V6 will also offer the best balance, but a 90-degree angle is needed to fit the two turbos.”

In this week’s interview with BMWBLOG, Dr. Friedrich Nitschke, BMW M CEO, refrained from offering further details on the powerplant, but we were left with an important tidbit of information: the new M3 will be lighter and will make extended use of carbon fiber parts.

With another year of production, the E90/E92 M3 might be the consumers’ last chance to grab a V8 naturally-aspirated engine.

The test mules shown below reveals the wide track specific to M products, as well as M front bumper, square LED headlights, large brakes and the signature four exhaust pipes at the rear.
