AMG boss confirms mild-hybrid model

SL65 Black Series� weight saving techniques will �definitely� be applied to future models

With AMG no longer focused on chasing big horsepower numbers, efficiency could quickly become the new performance benchmark for the Affalterbach-based tuner. Currently in development is a range of new diesels, advanced lightweight materials and construction methods, as well as a hybrid system for the Mercedes Benz performance workshop.

The information comes from AMG boss Volker Mornhinweg, who explained that the new environmentally-friendly measures are more likely to enhance a vehicle�s performance capability rather than erode it. �We have the technology to improve economy and performance � and you�ll see it sooner than you think,� he revealed during a recent interview with CAR.

While fuel-efficient diesels and hybrids are still several years away, we have already seen the first implementation of AMG�s new green initiatives in vehicles like the SL65 Black Series. Mornhinweg said that the car�s 661hp (493kW) output could be one of the last times such a high power rating is found on an AMG car. However, its advanced composite materials and other weight-saving construction techniques will definitely be applied to future models.

�Power is not a problem for us, so we�ll be focusing heavily on materials technology to lower weight and boost the power-to-weight ratios of our cars. And because they�ll be lighter, they�ll be more agile and engaging to drive,� he explained.

Such an initiative couldn�t come soon enough. The standard SL65 already tips the scales at 2,043kg (4506lbs), while the new Black Series weighs in at a significantly lower 1,870kg (4122lbs). Still heavy by most supercar standards but an indication of what can be achieved with the application of weight savings mods.

Beyond that, AMG will launch a mild-hybrid petrol-electric model using technology borrowed from the recently revealed S400 BlueHybrid saloon. Other �green� features will include engine stop-start technology, energy-recovery systems, and cylinder-deactivation. The other advantage of hybrids is the high instantaneous torque levels of their electric motors. �AMG is all about torque, and electric engines develop their torque at standstill,� Mornhinweg commented.

The launch date for the AMG hybrid is expected to fall around the end of the decade. Other initiatives include high-torque diesel models, although the number of AMG oil-burners would be kept low, possibly just a single model.
