Another day, another tuning story. This time it's Mercedes-Benz specialist Vath that has unveiled the V58 which is based on the SLK 55 AMG. The stock model comes with a 5.5-liter V8 engine delivering 360HP and 510Nm of torque.

The increase of the V8 engine's displacement to 5.8-liters along with the addition of a compressor and a series of other measures including a new exhaust system and recalibrated ECU, just to mention a few, push output to 565 horsepower and 770Nm or 568 lb-ft. The extra kick in the pants allows the V58 SLK to top out at 310km/h or 193 mph.

With 388 ponies from the 5.5-liter V8 under its hood, Mercedes-Benz's new E500 Coupe is by no means a slouch in the performance field, but that's not enough for German tuning firm Vath that has released a new proposal called the V50S.

Thanks to the recalibrated ECU, the addition of a sport air filter and a new sport exhaust system, the 5.5-liter V8 engine gets a jump from 388HP and 530Nm to 435HP and 575Nm (424 lb-ft) helping the German Coupe to reach a top speed of 280km/h or 174 mph.

A height-adjustable sport suspension that allows the driver to low the E500 Coupe's body anywhere between 20mm and 65mm and a high-performance brake system with 6-caliper brakes and 378 mm disks complete the list of performance modifications.

Vath's body kit includes a front lip spoiler, rear diffuser and boot lid spoiler, all made from carbon fiber, while the V50S rides on new 20-inch alloy wheels wrapped in tires size 245/30 R20 up front and 285/25 R20 at the back.

The German tuner also outfits the interior with a variety of accoutrements such as special leather trim, decorative carbon fiber inlays, and specific floor mats.
