Looking over the pantheon of fast cars around the world, Mercedes-Benz and its AMG-tuned models are nearly always somewhere near the top when it comes to quickly accelerating machines. But there's always room for improvement, right? Enter Renntech, the Florida-based tuning company that's been eking more and more power from the German automaker's wares for over 20 years.

Renntech just informed us of two new world records that its vehicles were able to set, the first by a customer and his CL65. The powerhouse machine used its ECU/TCU upgrade, ram air system, intercooler upgrade, high-flow exhaust and limited-slip differential to good effect, hitting a quarter mile pass of 10.62 seconds at 133.7 miles per hour to earn the title of the World's Fastest CL65.

Next up was Renntech owner Hartmut Feyhl, who's modified C63 (using unknown and under-development prototype products, says Renntech) ran down the quarter in 11.6 seconds at 125.3 mph. That impressive showing was enough to earn Feyhl the Worlds Quickest Trap Speed recorded for the C63. Congrats on the effort, Renntech.
