TopCar Panamera GTR based on Turbo S

If the Porsche Panamera Turbo S is a little plebeian for your tastes, you might want to give TopCar a call because they have just unveiled this bespoke model.

To start things off, the cabin is outfitted with premium leather seats and authentic crocodile leather on the dashboard, center console and armrest. Elsewhere, there's beautiful Karelian birch wood trim and gold accents which are applied on everything from the pedals to the window switches.

On the outside, the hatchback has been equipped with the Stingray GTR body kit. It has new bumpers, a bulging hood, widened fenders and modified doors.

The completed car is priced from €423,810 ($567,850) and includes €150,000 ($204,465) worth of "improvements."

Audi RS3 tuned by MTM

German tuner MTM has a power kit for the Audi RS3 Sportback that dials up output by more than 130 horses over the series 340 PS (250 kW / 335 hp) and 450 Nm (332 lb-ft) of torque.

A total power rating of 472 PS (347 kW / 466 hp) and 600 Nm (442 lb-ft) of torque is reached by means of a modified turbocharger and a new sport exhaust system which also provides the appropriate sound. MTM beefs up the braking system to match all that extra go too.

The RS3 by MTM is then good for a 0 to 100 km/h sprint time of 4.1 seconds over the series' 4.6. MTM also adds 19-inch bimoto wheels and lifts the V-max to 292 km/h (181 mph).

MTM offers more modest bumps in output to 410 PS (302 kW) and 424 PS (312 kW) for the less adventurous.

Total cost of the top-end package is €10,600.
