These are the road cars with the biggest engines ever made

Today the Brazilian market is used to low-displacement turbocharged engines, such as the 1.0 turbo three-cylinder. For a long time a 2.0 was considered large and larger engines, with six cylinders, were a luxury.

In the past, having large engines was synonymous with power and performance. And we are talking about units with more than 5 or 6 liters, such as the large North American V8s. Let’s remember here the five largest engines ever used in street cars.

1. Bugatti Tipo 41 Royale

The largest engine ever used in a street car did not come from the USA, but from France. The Bugatti Type 41 Royale, presented in 1927, is a superlative car in many ways.

Its engine is a 12.8-liter inline 8-cylinder, displacement similar to that of modern road trucks. This engine had overhead camshafts and three valves per cylinder, the power was 300 hp.

The Royale was Bugatti’s most luxurious car, measuring 4.30 wheelbase and 2.1 m wide, the length depended on the body and was above 6 m. The dry weight of 3,175 kg honors the hood ornament, which was an elephant balancing on its hind legs.

2. Dodge Viper

After the oil crisis in the 1970s, Americans switched to using smaller engines. The Dodge Viper returned with large-displacement units when it was launched in 1992.

The first version of its V10 was an 8.0, but in the second phase of the second generation it grew to 8.4 liters. This configuration had variable timing and yielded 604 hp.

In the third, and last, generation, the V10 of the Dodge Viper was updated again, yielding 654 hp. Preparers can get more than 1,000 hp out of this engine and without losing reliability.

3. Bugatti Tourbillon

Bugatti’s tradition in the past was to make agile cars with small engines, such as the old Tipo 51. When the brand was acquired by Volkswagen, it started to use large engines in the Royale line.

The Veyron and Chiron shared a W16 8.0. The Tourbillon, the brand’s current model, has a naturally aspirated 8.4 V16 developed by Cosworth.

This is the largest European engine of the modern era and produces 1,000 hp, with the help of the hybrid system the power rises to 1,800 hp. We put it below the Dodge Viper because the exact displacement is 8,355 cm³, against 8,382 cm³ of the North American V10.

4. Cadillac Eldorado

Cadillac was considering launching a V12 engine for its cars in the late 1960s, but eventually abandoned the project in favor of a larger V8. This unit, called the 472 Series, was launched in 1968 with 7.7 liters.

But it enters this list with the version presented in 1970 at Eldorado, an 8.2. In the USA the unit of measurement was cubic inches and Cadillac’s new V8 had 500 of them, it was the largest displacement of its time.

In 1970 the declared power was 405 hp, but this was raw data. In the following years came the oil crisis and this V8 started to use a lower compression ratio, until it stopped being offered in 1976. At that time it yielded only 192 hp of net power and 50 kgfm, a force similar to that of the 2.8 turbodiesel of the Toyota Hilux.

5. Chevrolet Suburban and Silverado

The North American brands’ big-block V8 engines continued in production during the 1980s and 1990s for pickup trucks and large SUVs. Ford had its 7.5 and Chevrolet used a 7.4.

At the turn of the 2000s, technology allowed more power to be taken from smaller engines, but Chevrolet went against this trend with the Vortec 8100. This 8.1 V8 engine was the last version of the Big Block launched in 1958 and was used in the Suburban 2500 SUV, the 2500 and 3500 versions of the Silverado and the Kodiak truck.

The power of this engine varied between 213 hp and 345 hp depending on the application, the torque was 62.9 kgfm in the strongest versions. This V8 was made until 2009, the year the Topkick truck was discontinued. Today GM has a more compact 6.6, derived from the Small Block, with 407 hp and 64 kgfm in its heavier models.
