Many sports cars stand out for their sleek designs and impressive performance, but some distinguish themselves even further through unique engine configurations. These unusual setups often challenge traditional engineering approaches and contribute to improved power delivery, handling, or efficiency.
The value of exploring sports cars with unconventional engines lies in understanding how innovation in engine design can shape driving dynamics and automotive history. This article highlights a selection of models that showcase creative and rare mechanical solutions, offering insight into the diverse ways manufacturers approach performance.
Mazda RX-7 Rotary Engine
The Mazda RX-7 is known for its rotary engine, specifically the 1.3L 13B REW twin-rotor design. This engine is notable for its compact size and high-revving capability. It delivers smooth power and unique performance characteristics compared to traditional piston engines.
The rotary engine’s design features rotors that rotate on fixed splines, producing power differently from conventional engines. Its configuration allows for a lighter and more balanced sports car, contributing to the RX-7’s handling and agility.
BMW i8 Hybrid Powertrain
The BMW i8 features a unique hybrid powertrain that pairs a 1.5-liter turbocharged three-cylinder engine with an electric motor. This combination delivers a balance of efficiency and performance.
The gasoline engine powers the rear wheels, while the electric motor drives the front wheels, providing all-wheel drive capability. The system offers smooth acceleration and improved fuel economy compared to traditional sports cars.
Suzuki Cappuccino Turbocharged 660cc Three-Cylinder
The Suzuki Cappuccino features a turbocharged F6A inline-three-cylinder engine. This 660cc engine was designed to meet Kei car regulations in Japan.
It is mounted just behind the front axle, creating a front-mid-engine layout. This contributes to balanced weight distribution and improved handling.
The engine uses belt-driven camshafts and can rev up to 9,000 rpm. The Cappuccino is a rare two-seater roadster produced from 1991 to 1998.
Audi TT RS Five-Cylinder Turbo
The Audi TT RS features a distinctive 2.5-liter five-cylinder turbocharged engine. It produces around 394 horsepower and delivers strong torque from a low rpm range, enhancing responsiveness.
This engine is known for its unique firing order and exhaust note.
The five-cylinder setup balances daily usability with sporty performance. It stands out among compact sports cars for its sound and character.
Porsche 718 Cayman Flat-4 Turbo
The Porsche 718 Cayman is equipped with a turbocharged flat-4 engine. This engine offers a balance between performance and efficiency. It can reach up to 7,500 rpm, which is high for a turbocharged motor.
The flat-4 layout helps lower the car’s center of gravity. This enhances handling and driving dynamics. Despite being smaller than the flat-six alternatives, it still delivers strong acceleration and responsiveness.
Bugatti Veyron W-16 Quad-Turbo
The Bugatti Veyron features a unique W-16 engine configuration. It consists of 16 cylinders arranged in a W shape, combining two V8 engines.
This 8.0-liter quad-turbocharged engine delivers exceptional power and performance. It propelled the Veyron to become one of the fastest production cars.
The W-16 engine remained in use for nearly two decades at Bugatti. It is notable for being the only 16-cylinder engine utilized in a production car.
