5.0-Liter V8 - Lexus LC500 / GS F / RC F

In a world where manufacturers are increasingly turning to turbocharging and hybrid power, it's nice to see a mainstream company like Lexus stick a naturally aspirated V8 under the hood of its flagship. That 5.0-liter is a gem, and it occupies a spot in every one of the company's current performance cars.

4.0-Liter Twin-Turbo Flat-Six - Porsche 911 GT2 RS

Porsche is able to push 700 horsepower through a six-cylinder engine and sell it to you with a four year / 50,000-mile warranty. Need we say more?

Subaru
2.5-Liter Turbocharged Flat-Four - Subaru WRX STI

The 2.5-liter motor isn't on this list because it's the newest, most technologically advanced motor out there—it's the opposite actually. It's been powering the STI in one form or another for nearly two decades, and while other turbo engines have become more seamless and efficient, the 2.5 remains raw and full of character. That's why we love it.

3.8-Liter Twin-Turbo V6 - Nissan GT-R

Like the Subaru's engine, the current Nissan GT-R has offered pretty much the same powertrain for its entire life. What makes it stand out is its ability to hold massive amounts of power, as we've seen many times in the past.

5.0-Liter V8 - Ford Mustang GT

Though it's not as wild as the flat-plane crank "Voodoo" engine, the 5.0-liter V8 in the current Mustang GT still deserves some recognition. It's a joy to rev out and listen to. Plus, it makes some serious power. American muscle at its finest.

2.9-Liter Twin-Turbo V6 - Alfa Romeo Giulia Quadrifoglio

The Giulia's 505-horsepower twin-turbo V6 is essentially a Ferrari V8 minus two cylinders. That explains why it makes so much power, and why it sounds so good.

Mercedes-Benz
Mercedes-AMG 4.0-Liter Twin-Turbo V8

The M178 4.0-liter turbo V8 found in pretty much every Mercedes-AMG car these days uses a "hot V" setup, where the turbochargers are mounted inside the V of the engine allowing for a quicker spool.

The brilliant new Shelby GT350 is arguably the performance bargain of the century. It can embarrass thoroughbread sports cars that cost way more. Even a loaded GT350R at $65,195 is reasonable.

  Just avoid dealer markups on early production examples.
Ford
5.2-Liter "Voodoo" V8 - Ford Mustang Shelby GT350

The GT350's engine stands out among most American V8s because it uses a flat-plane crankshaft.This allows for a higher redline and some seriously exotic sounds.

Bugatti
8.0-Liter Quad-Turbo W16 - Bugatti Chiron

The Chiron has easily the most outrageous engine configuration on this list. It has sixteen cylinders in the shape of a W rather than a V for space purposes, four turbochargers attached. Somehow, 1500 horsepower sounds about right.

Dodge
6.2-Liter Supercharged V8 - Dodge Challenger SRT Hellcat Redeye

The Hellcat Redeye uses the same engine as the Demon, which is now out of production. But instead of 840 horsepower it makes "just" 797 horsepower thanks to a redesigned hood. We'd say that's plenty.

Porsche
4.0-Liter Flat-Six - Porsche 911 GT3 RS

The new 520-horsepower flat-six in the 2019 911 GT3 RS is the most powerful naturally aspirated engine in 911 history. It revs to 9000 RPM, and makes a glorious noise.

Lamborghini
5.2-Liter V10 - Lamborghini Huracan and Audi R8

Though it might not be the newest engine on the block, the naturally aspirated V10 found in the R8 and Huracan is still one of the greatest out there. And if you go for the Huracan Performante, you get 640 horsepower.

Chevrolet
6.2-Liter Supercharged V8 - Chevrolet Corvette ZR1

Every engine in the Corvette lineup is fantastic, but the 755-horsepower LT5 in the top-tier ZR1 is the crown jewel. It's 50 percent bigger than the Z06 engine—so big, in fact, that it can't fit under the hood. As you can see from the above picture, there's a big hole to make room for the massive 2.65-liter supercharger.

Ferrari
3.9-Liter Twin-Turbo V8 - Ferrari 488 Pista

The new 488 Pista uses an upgraded version of the regular 488's 3.9-liter turbo engine, making 711 horsepower. Considering how little displacement is going on here, we'd say that's impressive.

Lamborghini
6.5-Liter V12 - Lamborghini Aventador S

The Lamborghini Aventador's massively powerful 6.5-liter V12 makes all the noises you'd expect from something so exotic. Plus, with the new S model and its rear-wheel steering, there's real fun to be had in the corners too.

Ferrari
6.5-Liter V12 - Ferrari 812 Superfast

The 812 Superfast houses Ferrari's most powerful naturally aspirated engine ever, a 6.5-liter V12 unit that makes a monstrous 789 horsepower. Unsurprisingly, it sounds ridiculous.

McLaren
4.0-liter Twin-Turbo V8 - McLaren Senna

McLaren has taken the 4.0-liter engine from the 720S and plopped it into the Senna, upping the performance to 789 horsepower without the help of hybrid tech. For a track car with a dry weight of 2641 pounds, that's a whole lot.

2.5-Liter Turbocharged Inline-Five - Audi RS3 and TT RS

Because the inline-five found the the new TT RS and RS3 has an odd number of cylinders, it's inherently cool. Also, if you listen to one at full throttle, you'll swear it sounds like half a V10.
