title：Best Sports Coupe: M240i vs Cayman vs Mercedes CLA45S

content：Which Sports Coupe Is Right for You?

Trying to pick between a fun driver’s car, a practical daily, and a power-packed ride? AutoCar’s Snowdonia test of the BMW M240i, Porsche 718 Cayman, and Mercedes-AMG CLA45S breaks down exactly what each offers. After analyzing their review, I’ll help you decide which coupe fits your needs.

Performance & Powertrain Showdown

Each car brings unique strengths to the table. The BMW M240i uses a 370hp B58 straight-six (same as the Supra) paired with a zippy ZF 8-speed torque converter—AutoCar’s reviewers praised its near-dual-clutch speed. The Porsche Cayman has a 296hp turbo flat-four; while down on power, its 1,400kg weight keeps it agile. The Mercedes CLA45S leads with 415hp but suffers from a slow gearbox at high revs.

Handling: Fun vs Balance vs Power

The Cayman stands out as the ultimate driver’s car. Its mid-engine layout and adaptive dampers deliver perfect balance—reviewers noted its steering feedback and body control are next-level. The M240i blends xDrive security with rear-wheel playfulness, ideal for daily drives and spirited runs. The CLA45S is front-led, offering raw power but less finesse in corners.

Practicality & Value

Price and usability matter too. The M240i and Cayman start at ~£46k (great value), while the CLA45S hits ~£61k. The M240i and CLA45S have rear seats (useful for small passengers), but the Cayman skips them for pure performance. For daily use, the M240i’s GT-like comfort edges out the stiffer CLA45S.
