Why does sports cars with V6 and V8 engines not have more horsepower?

520 views

I’m always wondered. Since a V8 engine from 20 years ago makes rougly the same as a I4 can produce today, how come we aren’t seeing more 500+ hp sports cars?

Crazy horsepower isn’t just a matter of the engine being super-powerful. You need a transmission/gearbox that won’t be utterly destroyed by that much power being put into it. You need a driveshaft and wheels that can withstand it. You want down-force on the drive wheels in order that the wheels not simply lose traction and spin when you put down that much power.

Otherwise the horsepower is useless.

Such cars do exist, but they’re hella-expensive for a reason. And it’s useful in very limited situations and potentially dangerous to be in control of something that powerful.

Not sure what you mean, there are more 500+ hp vehicles for sale today than ever before. The reason you’re not seeing more sports cars with that power is there aren’t as many sports cars, evidently we’ve decided we don’t want them anymore.

Generally speaking, sports cars aren’t really about pure HP numbers, not in the same way pony or muscle cars are. They’re about twists and turns, agility and precision of handling, not about straight line speed. Cars with 700, 800, 900 HP tend to be heavier, which makes handling worse. All in all, I’d say it’s mostly because people buying those cars don’t necessarily want or need that much HP.
