When you hear the name Loewenstein, you probably think it’s a Jewish tuner who is in the business of lowering cars. And that is somewhat true. But there is more to what they do, as shown here with this brilliant Loewenstein Mercedes CLA 45 AMG dubbed Saphir (Sapphire).

Being based on a CLA 45 AMG, Loewenstein Mercedes CLA starts out with 360 horsepower and 450 Nm of torque. The AMG four-cylinder turbo engine used in this model is undoubtedly one of the engineering marvels of our time. Still, with only one hour work and installing a plug&play power module, Loewenstein Manufaktur can boosts that output to 410 horsepower and 530 Nm.

Those who want still more can opt for a sport catalytic converter with a carbon fiber hood featuring an integrated air intake system complete with sport air filters. These changes will result in a total output of 425 horsepower and 540Nm – not a significant gain given the number of mods and their cost.

You are better off getting the 410 hp kit and spend the rest of your money on the wide body kit exclusively designed for Loewenstein Mercedes CLA. Consisting of an RS front spoiler and rear diffuser and a 3-piece rear wing, the carbon fiber kit adds 20mm to the girth of the little CLA at the front and 40mm at the back. Lowered suspension and a set of 20” concave wheels complement the kit.

Last but not least, Loewenstein offers a seres of interior upgrades for the CLA Saphir, including sport steering wheel, new upholstery, door and dashboard trims, and floor mats.
