What’s in an engine, and just about how can it positively or negatively affect the rest of a vehicle as a whole? Well if you are like me then you will share my view point that the engine is the heart and soul of a car and is a component that if not set up correctly could sour all of the other parts.
So with that being said we have just received work via autoblog that there are new spy images of the next generation heart of the mighty BMW M3. It has been known for quite some time that the 2014 BMW M3 would not carry on the current car’s naturally aspirated 4.0-liter V8. Instead, BMW had to come up with something smaller and more efficient. And that likely meant forced induction.
Rumors have been swirling about what form that engine would take: Turbo V6? Turbo inline-6? Supercharged V6? Each rumor had its own reasoning behind it, but the most talked-about prediction was a straight-6 with three turbochargers providing the boost. It sounded exotic at first, but then BMW unleashed its 3.0-liter triple turbodiesel in the 550d.
That news is welcome on two fronts: it represents a return to the engine configuration that we most associate with BMW performance, and it suggests a further development of the six-pot we’ve come to love in so many of the brand’s current models. The photos confirm that the engine is likely two have turbochargers at least (there are two pipes feeding the intercooler), and they do not contravene rumors that a third, electric turbo lies just out of sight.
Displacement figures for the engine still remain a bit of a mystery. It has been reported that the next M3 could be as voluminous as 3.3 liters, though it’s more likely, based on a BMW tech report claiming use of optimized, 500cc-cylinders, that the total size is 3.0 liters. In any event, everyone’s best guess about power output hovers around the 450-horsepower mark. Even the M3 has to take fuel mileage into consideration these days, so a return to a smaller-displacement engine was inevitable. Now we know how BMW intends to make sure that smaller doesn’t mean slower.
