Magnesium wheels, disc brakes, fuel injection, self - sealing tubeless tires, and a direct -
drive torque converter transmission were all evaluated or tested, but were dropped on the final prototype due to cost, engineering complexity, and lack of time to develop.
The exceptional engineering of the powertrain is enhanced by a stainless - steel exhaust pipe, an anti-roll bar, a front independent suspension, a sequential multi-point fuel injection feature, battery rundown prevention functionality and a lock -
up torque converter transmission.
In an interview with Drive (not The Drive), Peter Quintus, VP of sales and marketing for BMW's M performance division, said he sees manual gearboxes (and double - clutch gearboxes) going away in 6 - 7 years, replaced by
mainstream torque converter transmissions.
There is none of that dual - clutch nonsense when you are selecting drive or reverse are forced to wait while the DCT takes its own sweet time to figure out how to do
what torque converter transmissions have done for the better part of a century — make the car move.
Hooked up to a revised eight -
speed torque converter transmission, the big Porsche's accelerative abilities are somewhat shocking, sprinting to 62mph from rest in just 3.9 sec with the benefit of the Sport Chrono Package's launch function.
• Adapts the 4L60 or 700R4 automatic transmission (non-electronic version) for use in early - model vehicles, with or without an engine management computer • Includes instruction sheet, throttle valve spring for carbureted engines, a normally - closed fourth - gear clutch switch and wiring connector for the torque converter
Gear changes from the automatic happen quickly enough when in its default Comfort mode, though the CLS 63 AMG changes ratios with more of the casual effortlessness of a
conventional torque converter transmission than the lightning - fast, snap changes of a double - clutch unit.
In conjunction with
the torque converter the transmission is tuned to the special requirements of this engine.
I WOULD PREFER
a torque converter transmission instead of dual clutch.
The torque converter transmission shifts gears smoothly and is very efficient.
In Drive mode, it was ready to shift down as quickly as
the torque converter transmission could handle.
This unit responds extremely rapidly, dynamically and without the losses typical of
a torque converter transmission thanks to its low rotational inertia.
