Weistec Rockets the Mercedes-AMG GT to a New Speed Record

The performance specialists milked another 147 hp from the already mighty Mercedes…

Scientists of speed, the team at Weistec Engineering set a new quarter-mile record for the Mercedes-AMG GT on October 10, 2015, at the Auto Club Dragway in Fontana, Calif. Specializing in the design and production of high-performance parts for Mercedes’ already quick coupe, the Orange County–based crew enhanced the 503 hp car’s performance by adding its own high-flow air filters, high-flow downpipe and mid-pipe, vent-to-air (VTA) adapters, coilover suspension, and engine calibration. All together, the refinements retail for $9,700 before installation. The result? The car culled another 147 hp and 257 ft lbs of torque from the twin-turbocharged, 4-liter V-8 engine, taking it to a blistering 670 hp and 755 ft lbs of torque in total.

Burning up the track, the amped-up AMG GT made back-to-back attacks at the model’s record and took it with a top time of 10.8 seconds while traveling at 126.25 mph—a half-second faster than the factory version. But the new benchmark may soon be broken, as Weistec plans to return with its turbocharger upgrade and give it another go. (weistec.com)
