It's powerful alright - but you know it will be when it's got AMG in its name. Using the same 4 cylinder unit as its sibling the CLA 45 AMG, the new souped-up avatar of the GLA also has the performance exhaust package, which gives the car a deeper, meaner sound. The SUV is also lower, and so has more of a super hot-hatch stance and appeal really. We test it in Indian city conditions also to find out if it's really worth the fuss.
