This car looks very cool, but I doubt it'll do 0-60mph in 5.2 seconds; maybe if it had more modern tires, then yeah. Tires 15-20 years ago were crappy compared to today's tires. That's why a Brabus E V12 from 1996 was only capable of 12- or 13-sec 1/4 mile times, while it had a similar power-to-weight ratio and even output to today's E63 AMG S and M5 Competition Pack.
Almost everything is wrong about this cars states. Have you even seen a C43? compression ratio is 11.5 to 1. 0-60 is like 5.5. with traction control off, in the dry, and at about 55 degree fahrenheit. The car is probably heavier, and it can go over 155, its exhilarating. And re-check those engine stats. every amg is a little different. ;]
