Guess Which Automaker Will Now Get BMW's 600 Horsepower M5 Engine?

Sharing is caring, especially when it comes to horsepower.

It was only a matter of time before Jaguar's sensational lineup of supercharged engines was going to be phased out because the EPA wants pesky future generations to breathe clean air. Unlike its force-inducing cousin the turbocharger, superchargers are inherently inefficient because they get their power from the crankshaft of the engine, increasing load and throwing fuel economy to the wayside. The upside of this alternate method of forced induction is the absence of wait for power to build.

Eliminating impediments in the exhaust also unlocks the melodious soundtrack of popping V6s and V8s that characterize cars like the F-Type. Due to the thirsty nature of these engines, they will soon be replaced. The result is that the British automaker is running into a problem: as downsizing relegates larger engines to the minority classes, it's getting harder to justify the development costs of V8s. In the past, V8s were cost-effective because many of their components could be shared with V6 models. Jaguar even uses the same block for its V6 and V8 motors; it just removes two cylinders from the V8 and calls it a day. Now, even 6 cylinder engines are being phased out in favor of the turbocharged four-cylinder, raising the cost it takes to build the V8.

BMW is having the same issue, although it uses its V8s in many applications helping to justify the cost of development. To help give BMW another reason to keep building its V8, Jaguar Land Rover has just struck a deal with the German automaker to buy its latest generation of V8s in order to power high end Jags and high-output Range Rovers. Currently BMW builds the 4.4-liter twin turbo V8 that appears in cars like the 750i and M5, where it produces anywhere between 450-600 horsepower, but soon that will be replaced in favor of a twin-turbo 4.0-liter V8. This is the unit that will likely see its way into the next generation of JLR vehicles. We'll miss the supercharged engines of present, but at least the horsepower won't leave us anytime soon.
