The Mercedes-Benz C-Class range is one of the most popular luxury sedans in the world and has now gone through a mid life facelift which gives it more tech both on the outside and on the interior. The car now gets LED headlamps, a new infotainment system with a new user interface and an all-digital instrument cluster. The car also gets big upgrades under the hood with a new 1.5-litre engine that also gets the 'EQ Boost' mild hybrid technology. We also drive the updated Mercede-AMG C43, which gets more power, more torque and better performance making it faster and more usable than ever before.
