Datsun's line of stunning Z cars not only look good, they sound great. Give those straight-sixes a little room to breathe, and you'll go to redline at every opportunity.

Chevrolet Camaro
The V6-powered Camaro has gone from an unwanted compromise car to a full-blown performance machine in recent years. With over 330 horsepower and a wonderful soundtrack, we wouldn't look badly upon anyone who buys one of these instead of the V8.

Lotus Evora 400
The supercharged 3.5-liter V6 stuffed inside the new Evora 400 might be sourced from Toyota, but you wouldn't guess it by the noise it makes. It sounds more like a racing engine than anything else.

Jaguar F-Type S
Though you can option the F-Type with a wonderful-sounding supercharged V8, we think the V6 S variant is the pick of the bunch. Its exhaust makes similar crackles and bangs as its more powerful sibling, and you can have it with a six-speed manual.

Alfa Romeo Giulia Quadrifoglio
The 2.9-liter twin-turbo V6 found under the hood of the top-spec Giulia is essentially a Ferrari V8 with two fewer cylinders. So it's not surprising the engine sounds fantastic.

Any VR6-Powered Car
The not-quite-a-straight-six VR6 found in many great Volkswagens remains one of the great six-pot engines of the 1990s. It's still used today in some VWs, but will soon be retired.

Porsche 911 GT3
Porsche has made a handful of 911 GT3s over the years, and every single one of them sounds fantastic. Whether we're talking about the 996, 997, or even the new 991.2, each of their flat-six engines makes some of the most beautiful noises on the planet.

Ferrari Dino/Lancia Stratos
The mid-mounted 2.4-liter V6 found in the Ferrari Dino and Lancia Stratos is responsible for making a generation of enthusiasts love cars.

Alfa Romeo GTV6
Alfa Romeo's Busso V6, found in cars like the GTV6, is one of the greatest six-cylinders of all time, and makes a sound like no other. It's no wonder these cars are starting to climb in value.

BMW M3 (E46)
There's no mistaking the shrieking of BMW's S54 3.2-liter straight-six. The raspy, rev-happy engine found its way into several BMWs in the early 2000s, but we think the E46 is the pick of the bunch.
11 of 17
Jaguar C-Type
There's no doubt Jaguar's "XK" straight-six engines are classics. The perfect blend of noises that come together and out the exhaust pipe is something that can't be replicated on a new car.
12 of 17
Eagle Speedster
Of course, if you want to hear the very best Jaguar straight-six noise, you'll have to turn to Eagle and its restomod E-Types. Just one listen to that exhaust note and you'll be wondering just how irresponsible it would be to take another mortgage out on your house.

Acura NSX
While the new NSX may make a great noise, it's got nothing on the original. A naturally aspirated 3.0-liter VTEC Honda V6 was mounted behind the driver, and made one hell of a sound.
14 of 17
Toyota Supra (MkIV)
While it sounds great when stock, the 2JZ straight-six found in the Mk IV Toyota Supra is best heard when tuned north of 1000 horsepower.
15 of 17
TVR Sagaris
The goofy-looking side-exit rear exhaust pipes weren't the only cool thing about the Sagaris. It also had a 4.0-liter straight-six engine that put out over 400 horsepower and made a fantastic rumble.
16 of 17
Ford GT
Though it's branded as an EcoBoost, there's no mistaking the performance and aural pleasure coming from the new Ford GT's 650-horsepower 3.5-liter twin-turbo V6.
17 of 17
Nissan Skyline GT-R
The various turbocharged straight-six engines that found their way into Skylines over the years have always sounded great, but the end-of-the-line R34 might be the pick of the bunch.
