German tuning company, Prior Design, has gone to great lengths with their program for the Mercedes-Benz E-Class Coupe. For their latest work, the German aftermarket company has produced a complete package of upgrades for the E-Class Coupe, one that improves the luxury sports car’s overall profile, as well as its performance capabilities.

Among the aerodynamic goodies given to the E-Class Coupe by Prior Design include new bumpers on both ends of the car, revised side skirts, a new rear diffuser, a lowered suspension by about 35 mm, and a set of 20" wheels available in such colors as matte black, gloss black, gold, or silver. As an added option, Prior Design is also offering a roof spoiler for the car.

As far as the performance upgrades, both the E350 Coupe and the E550 Coupe were given ECU remaps, as well as new sport exhaust systems. These changes improved the car’s numbers by 74 horsepower, jumping the E350’s 3.5-liter DOHC V6 engine from 268 horsepower to 343 horsepower and the E550’s 5.5-liter DOHC V8 engine from 382 horsepower to 457 horsepower.

Prior Design’s whole gamut of improvements on the E-Class Coupe fits to exactly what we want to see from a tuning company: not too audacious, but enough to give it a fresh and more powerful look.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More

Prior Design made an impressive tuned up version for this vehicle. The styling look so refreshing and the power output was boost for more than 74 hp.

Mercedes has an elegant and luxurious styling. It’s a good thing that they have modified the aerodynamic kit of the car and increase its speed performance. BTW, it’s a great thing that they have boost the power as well.

E-class would be one of the most beautiful series in the line of Mercedes. I was captivated with the luxurious and elegance of this car. And its quite impressive that a v6 technology can produce a amazing figure like that!

Stunning! The elegance of this car really shows in its well crafted exterior! I love the golden platted paint job and wheels of this car.

A true class from Mercedez. Based on the design, its just the same as others. But on its performance, it separates itself.

Well, its a bit of a surprised that Prior Design actually didn’t touch the engine on this one, since thy are quite notable with that. But the ECU tweaks still did the trick.

I am really loving those bronze wheels that they did use on this one. You really seldom see some of these being used nowadays, which makes them really unique.

well, as expected from Mercedes car, it has an elegant styling but the performance
is kind of less powerful. Well, I hope other tuning company would attempt to upgrade this car.

What the hell! 74 hp? I think this power output is such a less powerful engine performance! I bet the Mercedes has made this car heavy!
