The Mercedes-Benz GLA 45 AMG has been spied once again, this time near the Nürburgring.

It will make its public debut in September at the Frankfurt Motor Show and most likely will borrow the A45 AMG's engine. It is a 2.0-liter, four-cylinder, turbocharged mill delivering 360 HP (265 kW) and 332 lb-ft (450 Nm) of torque.

Power will be sent to the 4MATIC system through an AMG SPEED SHIFT DCT seven-speed sports transmission with race start and double declutching functions, as well as three driving programs. Other changes expected over the standard model include a lowered suspension, more aggressive body kit and the usual AMG treatment for the interior.

The standard version will go on sale before the end of the year, while the hotter AMG model will arrive in early 2014.
