Why don't more cars make 100 hp/liter like sport bikes?

1 liter bikes make up to like 170 hp per liter, why don't more cars have like 3 liter 10krpm v8s basically 2 sport bike engines. they would make up to 510 hp? they would still have enough torque

Are there any engines you can buy that make over 100 hp per liter but are at lease 2-3 liters?

how do you make an engine rev higher that seems to be the key...

Well... I think you have never seen the Lancer EVO FQ-400 did you? it does 200 HPs per liter, and 200 lb-ft per liter, this from FACTORY.

You can use a car performance simulator to virtually see how a car would perform with any mod, you can design your own power/torque curves and see, try at http://www.nxgtrsim.com

What MIch said. You just don't see a lot of bikes with 150000 miles on them which have not had the engine torn down and rebuilt (if it lives that long). But I have seen a lot of 250000 mile car that have only had scheduled maintenance.

Reliability for one: Sport bikes redline at what, 10-12K? Bikes don't get miles put on them like cars on average, and really high performance sport bikes that are flogged, seldom go past 50K miles before the compression is shot and the engine needs rebuilt.

Gas mileage. High RPM engines are not as efficient at low RPM cruising speeds.

Emissions.

You owe it to yourself to "test drive" a used Honda S2000.
