Mercedes Unwraps New Hot Hatch: The A 45 AMG
The A 45 AMG is representative of the “AMG Performance 50″ strategy for the future, which is to run up to the 50th birthday of Mercedes-AMG in 2017. With a maximum output of 360 bhp and up to 450 Newton metres of torque, the AMG 2.0-litre four-cylinder turbo engine is the most powerful series production four-cylinder engine in the world.
As the world’s most powerful production hot hatch, the new A 45 AMG will go up against the likes of the BMW M135i and the Audi RS3.
“The A 45 AMG will enable Mercedes-AMG to appeal to new customers and tap new markets,” observes Ola Källenius, Chairman of Mercedes-AMG. “We are adding an extremely attractive model with exceptional performance to our range of unique high-performance automobiles.”
“With the new A 45 AMG we have well and truly achieved our aim of developing the most dynamic, powerful and efficient four-cylinder series production car,” comments Tobias Moers, Head of Overall Vehicle Development and Board Member of Mercedes-AMG. “With its impressive high-tech package and the performance-oriented AMG 4MATIC all-wheel drive, the A 45 AMG is a thoroughbred AMG through and through.”
The most powerful series production four-cylinder engine in the world
The high power and torque output and the combination with the performance-oriented AMG 4MATIC all-wheel drive allow the A 45 AMG to accelerate from zero to 62 mph in 4.6 seconds, while its top speed stands at 155 mph (electronically limited). This is accompanied by low exhaust emissions: the A 45 AMG already complies with the EU6 emissions standard which is not scheduled to enter into force until 2015, combined with the limit for the particle count per kilometre of 6 x 1011 which will be mandatory from 2017.

Black flics surround the large cooling air intakes at the sides. An interesting side view is accented by the AMG alloy wheels in twin-spoke design and the side sill panels with inserts in matt titanium grey.

Two square, chrome-plated tailpipes of the AMG sports exhaust system with exhaust flap add a finishing touch.
