The Mercedes-AMG A45 S 2025 stands at the summit of the modern hot hatch world, merging outrageous performance with all-day usability and high-end tech. With the headline “Mercedes-AMG A45 S 2025 review, the ultimate hyperhatch?” that captures its ambitious nature, this article delivers every detail and answers burning questions about why the A45 S is dominating headlines and redefining expectations in its class.
Performance and Powertrain
At its heart, the A45 S features the legendary M139 2.0-litre turbocharged four-cylinder engine, widely regarded as one of the most powerful for its size worldwide. This engine pumps out 415 bhp (416 PS) at 6750 rpm and a mammoth 500 Nm of torque available between 5000–5250 rpm. Paired with an eight-speed dual-clutch automatic and AMG’s 4MATIC+ all-wheel-drive system, the A45 S launches from 0–100 km/h in a stunning 3.9 seconds and tops out at a limited 270 km/h (168 mph).
- Engine: 2.0L turbo inline-4
- Transmission: 8-speed AMG DCT, AWD
- Power: 415 bhp
- Torque: 500 Nm
- 0–100 km/h: 3.9s
- Top Speed: 270 km/h
Design and Features
The 2025 update brings a subtle evolution: new headlights, AMG grille with an Affalterbach crest, reshaped bodywork, and an advanced AMG Performance steering wheel. Externally, it flaunts aggressive lines, 19-inch forged wheels, and an aerodynamic package including front dive planes, a rear splitter, a roof spoiler, and diffuser elements. The signature design doesn’t shy away from bold visual drama.
Inside, the dual 10.25-inch displays and MBUX infotainment system look futuristic, with sporty AMG bucket seats and extensive ambient lighting in 64 colours. Though the cabin brims with tech, some finishes don’t match the price tag’s luxury promise, with hard plastics and playful graphics.
Handling and Driving Experience
On the road, the A45 S offers a point-to-point urgency few can match. The multilink suspension and adaptive dampers give excellent body control, making twisty roads its playground. The rear sport differential and Drift Mode let drivers unleash serious tail-wagging fun, giving the car supercar-like cornering performance. Michelin Pilot Sport 4S tyres, ventilated discs, and finely-tuned electronics guarantee grip and confidence even when pushing hard.
While the A45 thrives on enthusiasm, it’s also comfortable in daily use. City driving is made easier with light controls, excellent visibility (except at the rear quarters), and a compliant ride. However, the firm seating, small boot (370L), and noticeable tyre roar are not ideal for longer journeys.
Technology and Safety
Expect a suite of advanced driver aids: adaptive cruise, blind-spot monitoring, lane assist, 360-degree cameras, and a full six airbags with 5-star safety. Entertainment is delivered by a punchy Burmester audio system and standard smart connectivity, Apple CarPlay, Android Auto, wireless charging, and mobile phone integration.
Practicality
Despite its compact, premium-hatch format, the A45 S is livable for five, with decent rear legroom and premium seat materials. The boot, though average for the class, is larger than the Audi RS3 but smaller than the BMW M2. Storage space for small items is somewhat limited, and long journeys are uncomfortable due to overly firm front seat cushions.
Comparisons and Value
Stacking up against rivals:
- Audi RS3: Sounds more exotic and offers greater chassis compliance, but trails in outright power.
- Honda Civic Type R: Delivers better smiles per mile but lacks the A45’s tech and AWD.
- VW Golf R: Cheaper but less sophisticated in handling.
- BMW M2: More fun in bends, but only available as a coupe.
With a price tag of over £63,000 , the A45 S ranks among the most expensive hot hatches. But all-wheel-drive capability, versatile auto transmission, and flagship AMG engineering make it a unique buy, especially for those who value cutting-edge tech and exclusivity.
