The outcome had us on the edge of our seats, as the quattro car had the lead in the beginning and eventually lost by a whisker.
The Benz's roofline peaks at 1.49 meters, 8.6cm lower than that of the RS Q3. There’s just 7mm splitting their lengths, and it's mostly due to the big chin spoiler of the GLA. Let's take a look under the hood as well. With the Audi, it's a five-cylinder engine that now produces 250 kW (340 hp) and 450 Nm (331.9 lb-ft) of torque. As a result of this boost in output, 0 to 100 km/h takes only 4.8 seconds, the exact same time as the GLA 45 AMG.
