Attention F10 BMW M5 owners: feeling a bit inadequate now that an electric-powered new kid on the block can beat you from 0-60 mph? Then Switzer might have a remedy. With just a few tweaks, the Ohio-based tuner has boosted the M5’s power figures from the factory-rated 560 hp and 500 lb-ft of torque to nearly 700 hp and 640 lb-ft (at the crank). Switzer is calling it the “M5 BMW should have built!”
The list of modifications is relatively short. A new engine control unit squeezes more boost from the twin turbos in the M5’s 4.4-liter V-8. Next, a Switzer exhaust and high-flow air filter round off the P700 package. The tuner didn’t provide any acceleration times, but we’re guessing it should shave off a couple tenths from the 3.7-second 0-60 mph run we recently achieved in an M5 (with the seven-speed dual-clutch gearbox). Better yet, Switzer says the new exhaust provides an aural benefit, with just enough punch to enter the cabin naturally, which means owners could theoretically disconnect the artificial engine noise currently produced through the M5’s stereo speakers.
The upgrade package is priced at $6995. Switzer will release more M5-specific items this summer, including wheels and carbon-nano brake pads. The P700 BMW M5 sounds promising and we’re eager to see how it performs against its German rivals and the surprisingly quick Tesla Model S.
