BMW is prepping a hotter coupe called the 3.0 CSL Hommage. It’s based on the new M4 CSL but features a ton of modifications to improve its on-track performance. A new video from the Automotive Mike YouTube channel captures the car undergoing hard testing at the Nurburgring race track.

It’s difficult to ignore the car’s performance aesthetic, with the front bumper featuring a gaping lower grille opening and big intakes. The camouflage can’t hide its sporty styling. The coupe has thick side sills, and the dual rear spoilers – one on the roof and another on the boot – will help to keep the car planted to the ground.

We don’t know any details about the car’s powertrain yet. Previous rumours suggested the car would deliver around 600 bhp and 516 lb-ft of torque. However, more recent ones point to the vehicle making just 560 bhp. BMW is basing the 3.0L CSL Hommage on the M4, with the M4 CSL packing a 543-bhp twin-turbocharged 3.0-litre inline-six engine producing 479 lb-ft of torque. 

The car’s unique and revealing camouflage suggests a six-speed manual transmission will be the standard gearbox. We expect all the power to route to the rear wheels, and an eight-speed auto might be an option. Helping the car’s performance capabilities will be a weight reduction, with the 3.0 CSL Hommage expected to weigh about 75 kilograms lighter than the M4 CSL.

The 3.0 CSL Hommage should be able to sprint to 62 miles per hour in 3.5 seconds, besting the M4’s 3.6-second time. The Hommage will also best the M4’s top speed, allegedly reaching just under 200 mph. The M4 tops out at 191 mph.

BMW could debut the 3.0 CSL Hommage before the end of the year, but the automaker hasn’t set a specific date. However, one report suggested BMW could reveal the car in November. The automaker will also build it in limited quantities, so its rarity will increase the price. It could cost as much as £650,000.
