2014 Chevrolet Corvette Stingray

Hennessey Performance Engineering has released the first details about their upcoming tuning program for the 2014 Corvette Stingray. The Texas-based tuner plans to offer two different performance packages for the C7 Coupe and Convertible. The first kit will use a supercharger to enable the model to develop up to 700 bhp (522 kW). The other kit will use twin-turbos for an output somewhere in the range of 800-1000 bhp (596-746 kW). Both packages will likely rely on the 6.2-liter LT1 V8 engine that normally develops 450 bhp (336 kW) and 450 lb-ft (609 Nm) of torque.

Hennessey also plans to offer a variety of accessories including cold air induction systems, cat-back exhaust systems and stainless steel long-tube headers. We can also expect a sport-tuned suspension, high-performance brakes and "wheel and tire upgrades."

The Corvette goes on sale in the third quarter of 2013, so expect the packages to show up several months after that.

Chevrolet Corvette C5 by Wittera

Corvette C5 owners hasn't seen a lot of love lately, so German-based Wittera has developed this retro-inspired conversion package.

Designed to mimic the C3 Stingray, the car is outfitted with a wide body kit which can be made from fiber glass or carbon fiber. Additionally, there are scissor doors and a distinctive rear hatch with a vertical window.

Last but not least, the company offers a wide range of hoods, spoilers and mesh inserts for a custom look.

Corvette Z06 by Romeo Ferraris

The Italian tuner Romeo Ferraris is at it again. This time they're taking on the Corvette Z06.

Romeo Ferraris takes the American import and drops its own compressor onto the LS7 7.0 liter V8 engine. The Vortech kit used includes a centrifugal compressor, an air-to-air aluminum intercooler and high-flow injectors. Total output goes from the standard Z06's 512 PS (377 kW) and 637 Nm of torque to 677 PS (498 kW) and 823 Nm.

Those new power ratings also come as a benefit of a new sport exhaust system and the Z06-RF is held in check by larger performance disk-brakes featuring 380 mm, 6-piston calipers for the front and 345 mm, 4-piston calipers at the back.

Front and rear wheels also differ in dimensions, with Romeo Ferraris fitting this Z06-RF with 19-inch rims at the front and 20-inch at the back.

Performance numbers include a 0 to 100 km/h sprint time of 3.3 seconds and if you keep going you'll reach 200 km/h (124 mph) in under 10 seconds. Top speed is 340 km/h (211 mph).

Romeo Ferraris also provides a new interior finish to add a European touch to this American muscle car. That includes an in-house "Commando" sport steering wheel by Romeo Ferraris, Recaro Sportster seats and leather touches to replace outgoing plastic moldings.
