Switzer Performance has launched an upgrade kit for the BMW M5 (F10) available for 6,995 USD. The tuner has taken a break from its aftermarket programs for the Nissan GT-R and various Porsche
models to focus on the German high-performance sedan. The car's
soundtrack has been improved thanks to a new high-performance, stainless
steel exhaust system.
It also features high-flow drop-in air filters and a removable engine
control module working together with the stock systems for a higher
boost from the engine's twin turbos. While the standard BMW M5's V8
4.4-liter twin-turbo produces 560 HP (412 kW) and 502 lb-ft (680 Nm),
the version modified by Switzer churns 700 HP (515 kW) and 640 lb-ft
(867 Nm).
The tuner has also announced starting this summer they will offer
carbon-nano brake pads and Signature alloys for all 2013MY (and later)
M5s.
