Even sports car makers are increasingly aware of the importance of offering vehicles that keep a keen eye on fuel economy: as reflected by the new generation of both the Porsche 911 Turbo (pictured) and the Turbo S.
Both models will boast new, advanced engines; as well as a new thermal management system; a PDK transmission; and a host of green technologies including a start/stop system and active aerodynamics. The result is that fuel consumption for both models is reduced by as much as 16 per cent: with the 911 Turbo and Turbo S registering fuel economy of 24.3mpg.
So what has made the difference?
The advanced engine is a bi-turbocharged 3.8litre, flat six-cylinder model that can produce 520hp in the 911 Turbo and 560hp in the Turbo S. Power is then transferred to the drivetrain through a seven-speed dual clutch transmission which also enables the start/stop system that can shut the engine off and trigger a coasting function.
There is no sacrifice in power, either. Motorists that opt for the 911 Turbo with Sport Chrono Package will note it travels from 0-62mph in just 3.2seconds: that's one tenth better than the previous 911 Turbo S. Meanwhile, the new Turbo S can travel the same distance in just 3.1seconds.
In addition, both models benefit from the introduction of rear axle steering that can boost circuit racing and everyday performance. It includes two electro-mechanical actuators as a replacement for the usual control arms: this allows the steering angle of the rear wheels to be adjusted by up to 2.8degrees.
When travelling below 31mph, the system will steer the rear wheels in the opposite direction whenever the front wheels are turned. This allows for strong performance around curves and offers a more dynamic steering response. Meanwhile, at speeds above 50mph, the system will steer the rear wheels parallel to the front wheels to offer the car a boost in stability.
The new versions of the 911 Turbo series are set to arrive on the market before the end of the year.
