### Introduction
The Goodwood Hillclimb has long served as a proving ground for automotive innovation, and this year’s edition lived up to that reputation. Amid the roar of historic classics and the whine of futuristic prototypes, Mercedes‑AMG stole the spotlight with the debut of its latest performance flagship: the CLA 45 4MATIC+. Boasting a staggering 680 horsepower from a novel triple axial‑flux electric powertrain, the model promises to redefine what a compact sedan can achieve on both road and track.

### Key Developments
At the heart of the CLA 45 lies a three‑motor axial‑flux arrangement, each unit delivering up to 226 kW (≈302 hp) and operating in seamless unison through Mercedes‑AMG’s 4MATIC+ all‑wheel‑drive system. The architecture eliminates the need for a traditional gearbox, allowing instantaneous torque vectoring and a claimed 0‑100 km/h sprint in just 2.9 seconds. Battery technology, sourced from the EQS platform, provides an 80 kWh pack capable of delivering over 500 km of WLTP range while supporting 800 V ultra‑fast charging—replenishing 80 % of capacity in under 20 minutes.

Kimi Antonelli, the 19‑year‑old Mercedes junior driver making waves in Formula 2, took the wheel for a demonstration run up the hill. His feedback highlighted
