- Top Spec Level 'AMG 45 S Plus' Example - Premium Plus Pack (£3,995) - Mercedes Manufacturer's Warranty until December 2022 - UK Supplied The latest CLA 45 S from Mercedes presents a big step forward over the older model. The sleek and elegant styling sets it apart from any other car in its class and an interior that has been upgraded in every possible way over the previous CLA 45. Accompanying the luxurious, well made interior and unique exterior styling, is the 2.0L turbocharged engine. The inline-4 cylinder produces a staggering 415bhp, launching from 0-62 in 4 seconds flat – this is the most powerful series-production 4-cylinder engine in the world. The 2.0L engine differs greatly from the 2.0L found in the CLA 35. For a start the engine has been flipped round 180 degrees, with the turbo facing the back of the engine bay. Mercedes have applied technology found in their 4.0L V8, with a host of engine upgrades such as forged internals and clever fueling. These are just a few of the reasons how Mercedes have managed such power from an engine of this size. The all-wheel drive setup has also been improved over the previous system. This time the AWD computer systems are constantly analysing data from sensors all around the car, which allows it to typically distribute a 50:50 ratio between axles rather than only being biased to the front wheels. Torque is also able to be limited up front so the CLA 45 S can enter a ‘drift mode’. These features give you an indication on how much knowledge and technology have been engineered into the latest CLA 45. The charm of an AMG has always been how they have been able to bring the best of every driving experience together into one package, which the CLA 45 S does effortlessly. The Mercedes CLA 45 S seamlessly combines supercar performance and comfort into an affordable every day coupé.
