Autoblog Podcast #339

Farewell, Zach Bowman; Pikes Peak 2013; Datsun; 2014 Ram lineup
Episode #339 of the Autoblog Podcast is here, and it's the last rodeo for Zach Bowman before he departs for other pastures. The crew this week consists of Dan Roth, Zach Bowman and Jeff Ross, who talk about the astounding records set at this year's Pike's Peak hill climb, the return of the Datsun brand name and the recently-announced 2014 Ram truck lineup. Of course, we start with the garage and end with your questions and comments. For those of you who hung with us live on our UStream channel, thanks for taking the time. You can follow along after the jump with our Q&A. Thanks for listening!

Jeep Wrangler 4xe's hybrid powertrain: Could it be headed to other FCA products?

On its own, the 2021 Jeep Wrangler 4xe plug-in hybrid is a big deal for the brand and the model line. It's the most powerful and most efficient Wrangler by significant margins, and it doesn't give up the off-road capability that makes the Wrangler so special. But another great thing about this hybrid powertrain is its potential to be transplanted into other FCA vehicles. Just to recap, the layout of the Wrangler's hybrid powertrain, front to back, is as follows: engine, clutch, electric motor, clutch, transmission. The engine is the same 2.0-liter turbocharged four-cylinder that's a standalone engine for the Wrangler. The transmission and electric motor are sort of one unit, with the motor and clutch replacing the torque converter of the transmission. And the transmission itself is the ubiquitous eight-speed ZF automatic gearbox. Its transmission code name is 8HP75PH. The ZF eight-speed is available in every FCA product with a longitudinally-mounted engine and rear-wheel drive or four-wheel drive, with variations in the amount of power and torque it can handle. Not only that, but the Ram 1500 and 2500 and the Jeep Wrangler and Gladiator all have powertrains that utilize the non-hybrid version of the 8HP75 transmission specifically. Even the gear ratios for that transmission as well as the 8HP70 used in the Jeep Grand Cherokee, Dodge Durango, Dodge Charger and Chrysler 300 are nearly identical to those in the 8HP75PH. And a Fiat-Chrysler representative confirmed that the transmission portion of the hybrid drivetrain is basically carry-over from the regular 8HP75. So a transplant could be a relatively simple process. As for which of these models would be the most likely to receive the hybrid powertrain first, the Jeep Gladiator and Ram 1500 would seem like good bets, since they likely have the most similar transmissions, and the Gladiator in particular because of its closely-related underpinnings to the Wrangler. Both are also highly profitable trucks that sell well and could justify the development costs of adapting another powertrain. And in the case of the Ram, there's the impending F-150 hybrid to think about. Although Ram isn't going after a fully electric model, a PHEV could be a nice middle ground. A potential limiting factor would be whether the hybrid powertrain would be sufficiently robust to handle heavy payload and towing demands, particularly over longer periods.

Chrysler flooded with over 8,000 Ram 1500 EcoDiesel orders in 3 days

The diesel, half-ton pickup has long been a Holy Grail to many truck fans, largely because of its potential to achieve both high payload and great fuel economy. Strange, then, that auto companies have seemingly been slow to react. However, Chrysler is finally wading into the pool for the 2014 model year with a version of its Ram 1500 pickup, and early claimed returns are showing the advantage of being first on the market. The Auburn Hills automaker has just revealed that its initial allocation of 8,000 EcoDiesel trucks has been filled by dealers in just three days.
That flood of orders came from February 7-10, and that strong surge of interest apparently amounts to a new Ram record for the number of customer orders placed for a vehicle in such a short period of time. In fact, EcoDiesel models accounted for over half of Ram 1500 orders over that period, despite the fact that the diesel option costs several thousand dollars more than a comparable gasoline-engined model. That impressive total did not come entirely as a shock to Ram officials, however: "We knew customers have been asking for it," Nick Cappa, Ram Truck communications officer, tells Autoblog.
The 2014 Ram 1500 with its 3.0-liter EcoDiesel V6 and standard eight-speed TorqueFlight automatic makes 240 horsepower and 420 pound-feet - a combination good for 9,200 pounds of towing. Despite that pulling power, its fuel economy is rated at 28 miles per gallon highway (the best among trucks in its class), 20 mpg city and 23 mpg combined. Four-wheel drive variants gives up a single mpg in all categories.
