For those Corvette C5 owners that think their cars could do with a little aero improvements, German aftermarket specialist Wittera has the answer: a new widebody aero package along with a light tuning program.[...]

Based on the Fiat 500 Abarth, the Motore Centrale R230 features a mid-mounted 1.4-liter engine that produces 230 PS (169 kW / 227 hp) and 330 Nm (243 lb-ft) of torque.[...]

Talk about a ‘Unicorn Project’ if there ever was one. Jon Olsson, the Swedish free-skier and alpine ski race, has made no bones about his love for finely tuned supercars, which includes his own stable of machines like theNissan R35 GT-R and the Lamborghini Murciélago LP670-4 SuperVeloce. Now, Olsson is collaborating with ADV.1 wheels to create and develop the “ultimate” Ultima GTR project. Details on the car are still not known with the exception of these jaw-dropping renderings, but if you know what the Ultima GTR is capable of, then you know that this car project is going to be a one sweet ride.[...]

Details are limited, but the styling package includes extended side skirts, a trunk-mounted spoiler and an aggressive rear diffuser.[...]

Some may remember the stark contrast of black and white used to set the original Mercedes E55 AMG apart from the pack.

One such baseball athlete has just received one of the most unique Bentleys we have ever seen thanks to a tuning shop in Miami, Florida.[...]

But if you want something a little more fresh, German tuning firm, McChip, has something special for you.

For the C63 AMG, McChip addressed the C63 AMG’s performance capabilities by introducing a new kit that they’re calling ’Stage 3’. As part of this program, McChip carefully remapped the car’s ECU, optimizing it and improving the performance figures that come with it. On top of that, the German tuning firm also gave the C63 AMG a new Cargraphic exhaust system which, combined with the ECU optimization, bumped up the vehicle’s output from 451 horsepower and 443 lb/ft of torque all the way up to 575 horsepower and 510 lb/ft of torque with a top speed of 193 mph.[...]
