Bentley Arnage, Technology Frontier

Bentley Motors continues the intensive development of its flagship Arnage, introducing a comprehensive body and body upgrade program for 2007, mated to a six-speed automatic transmission. as well as dynamism and sophistication. With the sleek exterior, styling cues inside, and the powertrain change under the hood.

The key to the increase in performance is the most powerful version of Bentley's legendary eight-cylinder engine at the company's headquarters in Crewe, England. In the performance-oriented Arnage Model T, a revised biturbo V8 engine delivers an impressive 500 hp. and 1,000 Nm of torque - an 11% increase in power and a 14% increase in torque over the top-of-the-line models. Performance and refinement are optimized at all speeds with ZF's latest 6-speed automatic transmission, which uses the latest generation of computer control. On the Arnage R and RL models, the power of the new engine increases from 400 to 450 hp and torque from 835 Nm to 875 Nm.

500hp Arnage. - a real driver car with much higher performance and a more rewarding driving experience. Also notable is the improvement in refinement and comfort of the 450hp Arnage R. The RL's long wheelbase shares the same performance as the enlarged rear cabin.

At the heart of the 2007 Arnage's development program is Bentley's 6.75-litre V8 engine. The unique engine, a core design that has served Bentley models proudly for nearly five decades, has been significantly modified to deliver 500 horsepower . and 500 hp. the Arnage T specification 1000Nm of torque - numbers that ensure Bentley's legendary torque is more amazing than ever. The top speed of the Arnage T has been increased from 168 mph / 270 km/h to 179 mph / 288 km/h, while the top speed of the 450hp Arnage R and RL has been increased. increased by 21 km/h. at 270 km/h.

When the first V8 engines were built in the 1950s, the short design inadvertently benefited the next generation of Bentley engineers. It's a very predictable design, with an all-aluminum body, five-head crankshaft and well-supported camshaft. The measures then taken laid the foundation for the longevity of the engine.

“People may lament the fact that Bentley first used the Arnage V8 in 1959,” says Brian Josh Motors, Bentley's Head of Powertrain and Chassis. “But the truth is that the basic design was so good that we kept improving it for almost 50 years.

“One of the reasons the engine was developed so successfully was the placement of the exhaust valves above the cylinder, which were originally designed to quickly dissipate heat to cool the engine. Decades later, this meant we could heat up the catalytic converter because it's the shortest route from the valves to the catalytic converters, contributing to higher emissions. That's just one of the reasons why this great engine is still running today.”

The first 6.25 liter engine produced about 200 hp. - 2007 more than doubled 6.75-liter V8 with 500 hp. and 1000 Nm of torque in T. This gradually increased the power of the V8, and the latest engine software is no different. The two new low inertia turbochargers work more efficiently at low engine speeds – they reach maximum turbine speed in half the time of the previous unit and provide a significant reduction in turbo lag and maximum torque at all engine speeds.

In addition, a reconfigured camshaft with a new tappet system provides revised valve timing and significantly improved tuning. These changes ensure better performance, longer life and compliance with EU IV and US LEV II regulations. Although the 6.75 liter 2007 engine produces around 300 hp more than its 1959 predecessor, fuel consumption is only 60% of the original engine and thanks to improved fuel injection and throttle control, exhaust emissions are 99% lower than the first Bentley.
