Another Exclusive on this week's show. The most powerful 4-cylinder engine in the world, and the fastest hot hatch on the planet. Nice, right? Well that is the all-new Mercedes-AMG A45 S. The top of the range of the new A-Class is quite the beguiling ride. Punchy, powerful and potent looks to boot, the A45 S looks even meaner in Sun Yellow. Watch our exclusive review - as we preview the new A-Class family - and yes the family is coming to India.
