Koenigsegg CCR tuned by edo Competition

The Koenigsegg CCR has enough power to shame most supercars, but that wasn't enough for one owner who found the whole driving experience a tad underwhelming.

To correct the misgivings, he enlisted edo Competition to modify the drive ratio and install a remapped ECU. As a result, the twin-supercharged 4.7-liter V8 engine hits its torque peak earlier and has an increased output of 891 PS (655 kW / 879 hp). Oddly, despite the extra power, the top speed was "reduced slightly" from 390 km/h (242 mph).

Furthermore, to fix the "notchy gear changes," edo engineers disassembled the transmission and replaced the plastic bushings with Uniball units. This results in improved acceleration and enhanced drivability.

Lastly, the cabin was outfitted with Alcantara upholstery, a redesigned center console, a new infotainment system, and a tire pressure monitoring system that has a display integrated into the dashboard.

GeigerCars has unveiled a new tuning package for the Ford Mustang Shelby GT500.

Dubbed the GT640 Golden Snake, the car features a matte gold exterior with a carbon fiber hood, a front lip spoiler and extended side skirts. Additionally, the company installed an adjustable H&R sports suspension and 20-inch alloy wheels with Michelin Pilot Super Sport tires.

Under the hood, the 5.4-liter V8 has been equipped with a supercharger, a revised ECU, and a stainless steel sport exhaust system. Thanks to these modifications, the engine produces 640 PS (471 kW / 631 hp) and 789 Nm (582 lb-ft) of torque. This enables the Golden Snake to rocket from 0-100 km/h in 3.7 seconds, before hitting a top speed of 295 km/h (183 mph).

The components will be available for purchase individually, but the demo model is for sale for €89,000 ($125,475).
