While some manufacturers are moving away from naturally aspirated engines towards more refined turbo- and supercharged variants, the V8 sedan is still a desirable automobile. From classic muscle cars, to high-performance sports cars, to modern full-size luxury cruisers, many automobiles remain loyal to the throaty eight-cylinder. In fact, some have incorporated turbocharging technology to push this popular power plant to new heights.
Our reviews cover every conceivable application for this powerful generator, and we don’t just give you the performance figures. We also cover how heavy these vehicles are on fuel, how well-appointed they are inside, and how practical they are in terms of passenger and cargo capacity. Whether you’re after a 4-door family hauler with a little extra kick, or a 2-door stylish roadster that is just as pleasing to the ear as it is to the eye, we have them all. You can rely on our expertise to help you find the perfect ride for you.
Most Reliable V8 Sedan Engines
Since V8s have fewer stroke cycles than smaller ones, they naturally last a bit longer. But that does not mean that they are all reliable. Some are unrefined, clunky, and noisy. It’s not overly surprising that the premium brands have put more work into refining their powertrains. Some of the most reliable eight-cylinder power plants, according to authorities, include those found in likes of America’s own Chevrolet Camaro SS and the Ford Mustang GT. Contributions from Mercedes-Benz and BMW in the form of the AMG S 63 and the 7 Series, respectively, also deserve a mention.
Sedans with V8 engines
Shoppers do not buy engines, though, they look at the machine housing the power plant. Since we know that the premium brands have designed the best hardware, it comes as no shock that BMW, Mercedes-Benz, and Audi dominate our top ten in this category. Some of our favorite V8 sedan cars include:
BMW 8 Series Gran Coupe - Holding our top spot, it comes outfitted with a 4.4-liter twin-turbo V8 that develops 523 hp and can launch the hefty machine to 60 mph in just 3.7 seconds with a throaty road. Aside from its athleticism, the 8 Series handles like a champ, and you will feel like one inside its plushly appointed cockpit.
Mercedes-Benz S-Class - The flagship sedan in the German manufacturer’s stable, the S-class gets access to an eight-cylinder under the hood. It displaces 4.0 liters to develop 463 hp and 516 lb-ft. With a larger focus on elegance and opulence, the S-Class is not quite as quick as its leading rival, but it still has more than enough oomph to throw its weight around and a soundtrack to die for.
Audi A8 - Yet another large executive vehicle, the A8 earns the final spot on our podium. It has access to a 4.0-liter twin-turbo hybrid powertrain that pushes 453 hp and 487 lb-ft to all four wheels. Since the hybrid system is dedicated to powering the onboard systems rather than optimizing performance, the A8 takes a slightly longer 4.5 seconds to make the 0-60 mph sprint.
What to consider before buying
The V8 was once the king of the road, balancing performance with efficiency to deliver the full package. But advances in automotive engineering have seen smaller six- and four-cylinder engines threatening its dominance with competitive outputs and far better fuel economy. Therefore, prospective buyers need to decide if this configuration is actually the best way to go.
Excellent balance of horsepower and torque
Eager power delivery when built right
Classic muscle car nostalgia
Quite a bit thirstier than more refined modern powertrains
Many brands have moved away from eight-cylinders
Not everyone will appreciate the roar
What are the best sedans with V8 engines?
While the Germans certainly have an excellent selection, such as the BMW 8 Series, Mercedes-Benz S-Class, or Audi A8, the Americans have their own flavor of powerhouse cars. The Dodge Charger SRT Hellcat is certainly worth some attention for those looking for more muscle than they know what to do with. The Italians also have the Porsche Panamera, with its distinctive styling and graceful handling.
Are there any cheap V8 cars?
Overpowered does not have to mean overpriced. There are a number of models with plenty of horsepower that do not ask for nearly as much as the luxury nameplates. Chevrolet and Dodge are both affordable names that place as much emphasis on value for money as they do muscle. The Chevy Camaro carries a cost of $37,000, while the four-door Dodge Charger will only set you back $29,995. If you do want something a bit more upmarket, the Chrysler 300 is quite reasonable at $30,040. You do not have to buy a 2020 vehicle, though. Vintage is often the way to go, so a used 2018 or 2017 model could serve you just as well.
