Mercedes-Benz has introduced a groundbreaking 4.7-liter V8 twin-turbo engine, featuring advanced third-generation injection systems and piezoelectric nozzles. This engine promises enhanced fuel efficiency and performance, setting new standards in the automotive industry.
Mercedes-Benz's new 4.7-liter V8 twin-turbo engine is a technological marvel, combining third-generation injection systems with piezoelectric nozzles for superior fuel efficiency and performance. This engine, known as the M278, is featured in models like the S500L CGI, CL500 BlueEFFICIENCY, and CLS500. It boasts impressive stats, including 435 horsepower and 700 Nm of torque, while meeting stringent emission standards. The engine's lightweight materials and advanced technologies make it a standout in the luxury car market.
In response to increasingly stringent emission standards, Mercedes-Benz has developed the 4.7-liter V8 twin-turbo engine, known as the M278. This engine marks a significant departure from the company's traditional large displacement naturally aspirated or supercharged engines. Instead, it incorporates BlueEFFICIENCY technology to deliver both power and efficiency.
The M278 engine is first featured in the S500L CGI, CL500 BlueEFFICIENCY, and CLS500 models. Here are the key specifications:
| Parameter | Value |
|---|---|
| Displacement | 4.7 liters (4662 ml) |
| Cylinder Size | 92.9 mm |
| Stroke | 86.0 mm |
| Compression Ratio | 10.5 |
| Maximum Power | 435 horsepower (320 kW) |
| Peak Torque | 700 Nm (516 lb-ft) |
| RPM Range | 1,800 - 3,500 RPM |
The M278 engine is paired with the 7G-TRONIC PLUS seven-speed automatic transmission, an enhancement of the classic 7G-TRONIC. This combination delivers impressive performance:
Mercedes-Benz has utilized lightweight materials such as magnesium alloy components to reduce the engine's weight. This, combined with low-resistance pistons and optimized exhaust systems, ensures smoother engine operation.
The third-generation injection systems, combined with piezoelectric nozzles, allow for multiple ignitions within milliseconds. This results in better fuel efficiency and reduced emissions.
The M278 engine includes several ECO features:
The M278 engine meets stringent European emission standards, with average carbon dioxide emissions of 244 grams per kilometer. This is a significant achievement, given the engine's power and performance capabilities.
Mercedes-Benz's 4.7-liter V8 twin-turbo engine is a testament to the company's commitment to innovation and sustainability. With its advanced technologies, lightweight materials, and impressive performance, the M278 engine sets a new benchmark in the luxury car market. Whether you're a fan of high-performance engines or eco-friendly technologies, this engine is sure to impress.
