The A 250 Sport comes standard with a seven-speed twin-clutch automated manual, dubbed 7G-DCT by Mercedes-Benz. There’s no manual option in Australia, but with the 7G-DCT, there’s arguably no need for one.Gearshifts are smooth and take-off from standstill is on par with the latest VW range of DSG gearboxes. When in Sport mode, the 7G-DCT rips through the gears with tremendous speed.We found though that it can sometimes be caught out with the wrong gear pre-engaged, but the result is just a slightly longer gearshift.In manual mode, it’s a delight. With the wheel-mounted paddles, you can race through the ratios, and, on downshifts (in Sport mode), with a perfectly matched throttle-blip.According to Mercedes, the A 250 Sport will hit 100km/h from standstill in just 6.6 seconds, which is pretty brisk for a hot hatch.(It also returns an average fuel consumption of 6.6 l/100km)
