RENNtech revealed the latest variation of their modified Mercedes C63 AMG line, dubbed the C74 Konzept. Now one might think that 74 means they’ve upped the engine size form 6.2 to 7.4 liter, but no! That actually refers to the 74 inch width of the rear wheel track which gives it a wider scarier presence.

Of course some people think that the standard C63 is already way too cheesy and glitzy, so they’re not going to like the new exterior part that make the C63 even more flash. They’ve used the same recipe of front splitter, side skirts, and rear diffuser plus a rear wing, all made of carbon fiber, for this car. But this being a new experimental model, they’re all insanely bold.

New wheels and tailpipes also affect the style of the car by a great deal. Meanwhile the modified engine offers 605 HP, enough for a top speed of 204 mph.
