ZF showed off their nine-speed automatic (9HP) to German magazine Autozeitung, using a Mini Cooper S mule. Three automakers have already agreed to purchase the 9HP, one being Chrysler, and one almost certainly being another traditional ZF customer, BMW. The magazine pointed out that the 9HP is extremely compact — it has to be, to fit into a Mini — and that ZF had worked hard on breaking back into the front wheel drive market, with its eye on the efficient double-clutch transmissions which have been increasing in popularity.
The transmission, to be used in future Chrysler front wheel drive products starting around 2013, weighs under 190 lb, including the transmission fluid; the decision to use nine speeds was, according to the magazine, based on a detailed cost-benefit analysis rather than merely trumping eight-speeds.
The compact size was achieved partly by moving the oil pump, changing two of the switching elements from the usual couplings to new forms. The transmission can go up to 480 Nm input (around 354 lb-ft) which is more than enough for the most capable four-cylinder or V6 engines ever produced by Chrysler, and then some.
The magazine seemed happy with the feel and operation of the transmission. (Thanks, K. Oellinger; see more ZF HP9 details.)
The Ram 1500 faced down the aluminum-bodied Ford F-150 and new Chevrolet Silverado in Motor Trend’s half-ton truck shootout. The three contenders were put through a broad array of testing, including a 260-mile drive through California and Arizona. Measurements included: Testing without load: 0-60 mph and 1/4-mile acceleration, 60-0 mph braking, and maximum lateral grip (Ram was Limits-handling without load: closed-course cornering, braking, [...]
The 2015 Dodge Charger squad has been tested in police trim for the first time, but since it kept the five-speed automatic, it has turned in numbers similar to past years. While the eight-speed V6 Charger does 0-60 in 6.6 seconds, the five-speed was timed at 8.05 seconds by the Michigan State Police. The civilian 2015 Charger gained acceleration from the eight-speed, [...]
Months after unconfirmed reports made it to Allpar’s pages, the power of Automotive News, in the person of reporter Larry Vellequette, pried a key fact from Chrysler executives — that they cast and build “Ferrari” engines for Maserati. As our sister site pentastars.com reported, the engines are actually cast in Kokomo, and machined in the Trenton Engine plant, using a mixture of [...]
