2023 CLS-Class Performance

The CLS is offered as standard with a 3.0L inline-six gas engine developing 362 horsepower. The power is transmitted to the road via the Mercedes 9G-Tronic automatic transmission, allowing the CLS 450 4Matic Coupe to complete the 0-60 mph sprint in 4.8 seconds. The top speed is limited to 130 mph. Unlike the E-Class, there isn't a slower, four-cylinder '350' model available on the CLS.

Engine and Transmission

The CLS 450 Coupe uses the turbocharged M256 inline-six that replaced the M276 V6 of yesteryear. It's powerful and refined and develops 362 hp and 369 lb-ft, the latter available from only 1,600 rpm. With the EQ Boost system, any trace of turbo lag is eliminated and engine response is velvety smooth, yet forceful and instantaneous. It gels perfectly with the nine-speed torque-converter automatic transmission, which shuffles through the gears unobtrusively. EQ Boost can add 21 hp and 184 lb-ft of torque, but only for short periods.

The 4Matic system adds immeasurably to the CLS's surefootedness on wet or slippery roads and is ideal if you live in an area that experiences snow in winter. Sprinting performance is superior thanks to the added traction and there is no scrabbling for grip.
