Under the hood, the M5 Dark Edition houses a tuned version of the 5.0-liter V10 accompanied by upgrades including a recaliberated ECU, high-flow air filters, catalytic converters and a newly developed performance exhaust system. In the process, the output has been improved from 500 horsepower and 521 Nm (384 lb-ft) to 555 horsepower and 560 Nm (413 lb-ft). Sans the electronic speed limiter, the M5 Touring can hit a top speed of 305 kmph (190 mph), needing just 4.2 seconds to accelerate from 1-100kmph, and under 10 seconds to accelerate from 100kmph to 200 kmph.
Other tweaks include a new aero kit comprising of a front apron with additional lights, a rear apron that allows the fitting of bespoke exhaust tips and a roof wing. Four new 20-inch alloy wheels painted in black with a silver rim and shod in Dunlop tires size 255/35 R20 at the front and 285/30 R20 at the rear complete the set of modifications done by Edo Competition to the car’s exterior. In the inside, the company has on offer a wide range of leather upholsteries and carbon trim parts, to a new speedometer with white dials and a backlit logo.
