Mercedes reveals the A45 AMG

Packing some serious firepower...

Mercedes-Benz has revealed the A45 AMG ahead of the public reveal at the Geneva Motor Show in a couple of weeks. This new model is a radical departure for AMG, having only 4 cylinders and a predominantly front wheel drive power delivery, but they are sticking to their core attribute of brutal amounts of power.

Based on the new A-Class model, the A45 marks the smallest AMG model ever, they’ve previously never gone smaller than the C-Class for a production model. As we’ve mentioned, the A45 will be using a 4 cylinder engine, but it’s pretty special. Still handbuilt by AMG engineers, the 2.0 litre turbocharged engine puts out a staggering 355 bhp and 332 lb/ft of torque. That’s the highest specific output of any 2.0 litre engine ever fitted to a production car.

These incredible power figures mean the 0 – 62 mph dash is taken care of in just 4.6 seconds on the way to a 155 mph limited top speed. Mercedes even claims an average of 34 mpg and just 161 g/km of CO2.

In order to handle all that power, drive is sent through a seven speed dual clutch paddle shift gearbox to a 4Matic haldex four wheel drive system. This is the same type of system seen on the VW Golf R32, meaning it is predominantly front wheel drive, with power going to the rear wheels when slip is detected at the front. Mercedes are making big claims about how they’ve tuned the system to give a typically AMG feel, but to us that ‘AMG feel’ is power oversteer and lots of it, so we’re intrigued to see how they’ve managed to tune it.

Visually the A45 AMG isn’t too dissimilar to the regular A250 AMG Sport model, with a prominent front splitter, wide cowled air intakes and the standard two-car AMG grille. The rear has a faux diffuser and twin exhaust outlets, while the car rides on 18-inch alloy wheels. Inside the A45 looks very impressive with a woven carbon fibre style dashboard, winged sports seats and lashings of carbon fibre.

The A45 is up against two main rivals – the 316 bhp BMW 135i which plays the purist and price cards as it is rear wheel drive and available as a manual for just £29,995, and the new Audi RS3 which should have 340 bhp but come in at near £40,000. The A45 is set to sit between them at around £36,000 plus a fair whack for more options when it goes on sale in July.
