That is not true. My new 2019 Mustang EcoBoost has 310hp and 350ft/lb of torque (key for acceleration) and is considered an entry-level mid-range vehicle. As recently as the early 2000s anything past 300hp was considered a race car.

Advanced software (in modern automatic transmissions for example) and material advancements have made all the difference in the advancement of combustion engines in the past 15 years and I firmly believe that technology can be pushed even further. I want to see 4 cylinder engines pushing 500hp, sounds like a pipedream now but so did 300hp when I was a kid.

If you want to see what happens when you perfect the marriage between a combustion engine and an electric motor w/ batteries, do some research on the McLaren P1.

The Mercedes-Benz M133 engine already pushes almost 400hp out of a 2-liter 4 cylinder. I imagine they'll all grenade themselves before they hit 50,000 miles but I guess we'll see.

horsepower is not fuel efficiency
