The days of naturally-aspirated performance cars are rapidly coming to an end as car manufacturers chase performance without sacrificing gains in efficiency and fuel economy. These are six of the finest naturally-aspirated cars which are still on the market.

The following list, put together by Drive Tribe, doesn’t name every all-motor performance car still on sale but does focus on some of the very best.

The first in the list is the Ford Mustang. While both the Mustang EcoBoost and Shelby GT500 models feature forced induction, the Mustang GT retains an NA V8 and so do the GT350 and GT350R twins. The Mustang also happens to be the world’s best-selling sports car so it seems unlikely Ford will ditch its naturally-aspirated offerings anytime soon.

The second car mentioned is the Lexus LC, available with either a V6 with hybrid assistance or with a big 5.0-liter V8 and it’s this engine which just so happens to be one of the finest currently on the market. Next comes the Porsche 911 GT3 which features a screaming six-cylinder engine with 493 hp in standard specification. This engine, albeit with a few alterations, is also found in the GT3 RS and Touring models and now, also in the 911 Speedster.

The Audi R8 is also mentioned as it uses a powerful V10 engine which howls unlike any other powertrain on the market. The same engine is also offered in the Lamborghini Huracan. The final two models on the list are the Lamborghini Aventador SVJ and Ferrari 812 Superfast but the Aston Martin Valkyrie has also been thrown in there despite not yet reaching the hands of customers.
