Mercedes will unveil its A45 AMG hot hatch in Geneva.

Mercedes-Benz' fire-breathing A45 AMG hot hatch will debut at the 2013 Geneva Motor Show. It was though that the A45 AMG might arrive at the Paris Motor Show, but Mercedes skipped the biennial show in favor of Geneva, which is where the standard version of the car made its first public appearance.

Mercedes-Benz confirmed its plan to debut the A45 AMG in Geneva with Autocar. Following its March debut, the A45 AMG will hit the European market in July. There are no current plans in place to sell the A45 AMG in the United States.

The BMW M135i-rivaling A45 AMG is expected to arrive in Geneva with a turbocharged 2.0L gas engine developing 349 horsepower and 332 lb-ft of torque. Mercedes' seven-speed gearbox will send power to all four-wheels.

Although nothing is official at this point, early estimates suggest the A45 AMG will be able to accelerate from 0-62 in 5.1 seconds with a limited top speed of 155mph. However, Mercedes will also offer a performance package that will eliminate the electronic nannies, lifting the car's top speed to 168mph.

Despite that blistering performance, the A45 AMG's combined fuel economy is said to be better than 40mpg (imperial) on the European cycle.

When the Mercedes-Benz A45 AMG goes on sale next summer it will carry a base price of about £36,000 ($58,000)
