Nobody drives a Ferrari 458 Spider and says it needs more power. Except for John Hennessey . He twin turbocharged one.

 

A bit more than 2,000 hp in a Gallardo equals a quarter mile time of 10.293 and a mile in 23.479 at 230 mph. Pretty much unbeatable performance.

Some cars are so historic and so magnificent that modifications would only deface their perfection. Here's our guide to not ruining cars that don't need your ideas or input.

 

A 651-horsepower Ferrari FF. A 1988 Audi 80. A half-mile drag race at an airstrip. Doesn't sound like a fair fight, does it?

The car on the top is a C63 AMG Black. It is a Mercedes C-Class with a bigger engine, revised suspension, and revised bodywork. The car on the bottom is the Brabus Bullit. It is a Mercedes C-Class with a bigger engine, revised suspension, and revised bodywork. How are they different?

What happens when you put a swanky interior in a compact car? You end up with the most modest luxury vehicle ever.

For decades, the import tuner scene in America was dominated by three magic letters: JDM. If you wanted a hot Japanese car, you wanted JDM parts, JDM engines, JDM style. Along the way we Americans developed our own aesthetic, and now, in a strange twist, it seems the Japanese are beginning to copy us.

 

Say, remember that 736-horsepower Volkswagen Golf from a few months ago? It's okay... I guess. I say that now because I just found one that's even more psychotic.

Some of us drive cars that are fast. Some of us drive cars that are furious. (I've owned ones that are neither.) But it takes a lot to make a car that's both fast AND furious ? about $70,000, according to this estimate.

Do you own a McLaren 12C Spider ? Do you hate its subtle styling, reminiscent of classic car design of the 1960s and '70s? Great! You can pay Gemballa $35,000 to ruin it for you.
