Patfromigh pointed out that, according to publicly available Department of Energy files, Chrysler is experimenting with a mild hybrid, similar to the General Motors system. Both use a belt alternator starter/belt starter generator (BAS/BSG) to provide stop-start, regenerative braking, and low-speed motor assistance. Chrysler’s main difference from GM is the use of an electric belt tensioner, and much greater use of fuel shutoff during deceleration (“iDFSO”).
Current Chrysler vehicles with automatic transmissions already use iDFSO, which cuts off the fuel supply to the engine when the driver coasts, as long as all the right conditions are met (hot catalyst, sufficient battery power, warm engine, etc). GM had a similar system in use decades ago, but for manual-transmission cars (when coasting in gear).
The BSG system was added to allow iDFSO all the way down to a full stop; standard iDFSO is normally available down to 15 mph, and the alternator/starter provides the rest of the capacity. The electric belt tensioner is needed to tighten the belt during power generation, and loosen it during normal motoring. Enhanced voltage regulation and fluid temperature control are also part of the system, as they are in Ram 1500, to cut parasitic losses.
From these documents, it appears that the Department of Energy program to work on fuel reduction has resulted in a transfer of technology to production vehicles — at least, to the 2013 Ram 1500.
It has been years since Allpar first reported on the future launch of a new Jeep Wagoneer, and the dropping of the Dodge Caravan. With Wagoneer on the books, Chrysler planners may have had mixed feelings about the sudden success of the Dodge Durango. They wanted to drop the Durango for a more-profitable Wagoneer (essentially a Durango with the Grand Cherokee suspension design [...]
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 [...]
Alfa Romeo will launch the second new car in its attempted comeback next year, on the brand’s 105th anniversary. Anonima Lombarda Fabbrica Automobili (roughly, Lombarda car making company) — or ALFA — was born on June 24, 1910. Their next car will be unveiled on June 24, 2015. While Alfa Romeo’s leader, Harald Wester, has said that the company is creating all [...]
The Challenger Hellcat is a hot image car for Dodge, and the brand’s leader has already said he wants to get as many out to the public as possible, suggesting to dealers that they not tack on $10,000 (or higher) surcharges as they did to hot cars in the past — from Vipers to PT Cruisers. While his calls may [...]
The 2015 Chrysler 300C has been inadvertently revealed by Chrysler itself, in an optional image for its navigation systems. As Allpar sources predicted, the car has dropped the chrome underneath the headlamps and moved the Chrysler wings to the top of the grille, but otherwise is rather similar to the current model. The grille has grown to be Audi-oversized in this [...]
