The user reiterates earlier rumors that the hyper sedan will deliver 25 extra horsepower. That will take the M5 from 0-62 miles per hour in 3.3 seconds and from 0-124 mph in 10.8 seconds, with a top speed of about 190 mph. Motor 1 reports the car will get an extra 37 pound-feet of torque, raising the specs of the 4.4-liter biturbo V8 to 625 hp and 590 lb-ft of torque, giving it an extra 22 ponies above the Mercedes-AMG E63 S but 37 lb-ft less torque.
Carbon ceramic brakes, according to the Bimmerpost member, are not included, which if true is a departure from prior conventional wisdom but may help keep the price down for the tuning package.
Elsewhere, there's reportedly Sports Exhaust — reportedly not the full lightweight titanium exhaust, but "more cracks and louder" — a lowered and firmer suspension, and Y-spoke alloy wheels. There's an M carbon engine cover and Competition illuminated door sills. And it will come with black badging, with a rear M5 Competition logo, black front and side grills, blacked-out lower rear bumper and a high-gloss black rear boot lip.
Pricing isn't yet clear but will reportedly hew closely to the price for the previous-gen M5 Competition Package, which was about $7,300. The all-wheel-drive 2018 M5 starts at $103,595, meaning the Competition Package would nudge it up to around $111,000. Production reportedly begins in July, with deliveries starting in September.
BMW is expected to make the unveiling May 8, so we'll get official details then.
