On May 20, the 2023 BMW M4 (picture | configuration | inquiry) CSL made its debut! This lightweight, high-performance coupe is the company's latest M-series product, which coincides with BMW's celebration of the 50th anniversary of its iconic performance brand. The maximum output power of the BMW M4 CSL is 543HP, with an acceleration of about 3.6 seconds per 100 kilometers. The overseas starting price is 140895 dollars, which is equivalent to 946000 yuan at the current exchange rate. It will start production in July this year. BMW M4 CSL is an exclusive model. BMW plans to produce only 1000 vehicles worldwide. This coupe is based on the improvement of M4 Competition, making it the fastest mass-produced BMW in history. It took only 7:20.2 for the M4 CSL to complete a lap at the Nordschleife track in Nurburgring. In order to win the reputation of "competition, sports and lightweight", BMW engineers removed some parts of the body, including the rear seats. The roof, engine cover and trunk cover are made of carbon fiber materials. As well as reducing the weight of double kidney grille, tail lamp, foot pad and automatic air conditioning device by 3.6 kg. Unlike the new M4 interior, the M4 CSL will not be equipped with BMW's latest curved screen. On the contrary, the highlights of the interior are M Carbon full bucket seats and carbon fiber center console, both of which are unique to CSL.

In addition to removing the rear seats, the front seats were also replaced by M Carbon full bucket seats, which also reduced 53 pounds (24 kg). With carbon ceramic brakes, forged wheels and lighter springs and struts, another 46 pounds (21 kg) were lost. Reduce the sound insulation function and use lightweight sound insulation materials, reducing 33 pounds (15 kg). The titanium alloy exhaust pipe was also used (4 kg less). Compared with the standard version M4, the total weight is reduced by 240 pounds (109 kg) - roughly the same as that of the 2003 BMW E46 M3 CSL. The curb weight of this coupe is 3640 pounds (1605 kg). The 2023 BMW M4 CSL is equipped with a 3.0-litre twin-turbocharged in-line six-cylinder engine, with an output power of 543 hp (550 PS/411 kW). Compared with the M4 Competition, the output power is increased by 40 hp (41 PS/30 kW). At the speed of 2750 to 5950 rpm, the maximum output torque is 649 N · m. The transmission system is Drivelogic's 8-speed M Tiptronic transmission, which adopts the rear wheel drive system. The driver can activate the manual mode through the carbon fiber shift paddle behind the steering wheel. In the manual mode and acceleration state, the transmission will not be forced to upshift. In addition to further reducing the weight of the engine, the boost pressure has also increased, from 24.7 psi of M4 Competition to 30.5 psi of CSL. BMW said that the M4 CSL accelerated from 0 to 60 miles per hour (96 kilometers per hour) in 3.6 seconds. It only takes 10.5 seconds to reach 120 mph (193 km/h). 0.2 seconds faster than M4 Competition (but 0.2 seconds slower than M4 Competition xDrive). The maximum speed is limited to 191 mph (307 km/h).
