Manhart unveiled a few months ago an upgrade program for the M5 and now they have developed a tuning kit for the 1M Coupe. Known as the MH1 S Biturbo, the main focus was on the engine that at first got a software update, followed by a new air guide with a carbon airbox and custom downpipes. There’s also a bigger charging air cooler and a larger water cooler. As a result, this custom BMW 1M Coupe is 125 hp (93 kW) more powerful than the standard model, being capable of outputting no less than 465 hp (347 kW). Other modifications include a special MHR front spoiler, new tail diffuser, carbon motor cowl and trunk lid, along with mirror caps made from the same lightweight material. We also notice the 9x20 front wheels with Continental Sport Contact 5P 245/30 ZR20 tires and the 10.5x20 rear wheels wrapped around in 295/25 ZR20 high performance tires. Inside the cabin there are BMW performance seats and an additional MHR display where the driver can see all the relevant data, like motor temperatures, maximum torque used and acceleration values.
