Autoblog Podcast #523 | BMWs, Trackhawk and Mazda's new engine technology

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Joel Stocksdale. We discuss a couple of BMWs, the upcoming BMW X7 three-row SUV and our short-term BMW M760i with a turbocharged, 600-horsepower V12. We also cover the week's news, including Mazda's nifty engine technology it will roll out in the next few years, as well as pricing on the new Jeep Grand Cherokee Trackhawk. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want buying advice of your very own, send a message or a voice memo to podcast@autoblog.com. (If you record audio of a question with your phone and get it to us, you could hear your very own voice on the podcast. Neat, right?)

Why the 2019 Ram HD Power Wagon still doesn't have a diesel

We were all pleased to see that the all-new 2019 Ram HD pickup truck was going to have an off-road Power Wagon variant again. In a world of high-speed, dune-busting off-roaders, the slower, trail-focused Power Wagon is refreshing. But we were surprised to see that, yet again, Ram wouldn't offer a Cummins diesel engine with it. It seems like such a perfect match with low-down torque and better fuel economy. So we asked Jim Morrison, the head of Ram, what's going on. As it turns out, there are a couple of reasons for only offering the gas engine. First is the fact that Ram can't fit the standard winch behind the bumper when the longer straight-six turbodiesel is in the truck. And since the Power Wagon has always had a winch, and it's a big part of the truck's image, that would be a non-negotiable. Another reason is that the big, heavy diesel engine requires slightly different suspension that has worse articulation than the setup for the gas model. That would also hamper the truck's off-road capability, and again would not be acceptable on the ultimate off-roading Ram. Of course this all left us wondering whether there might be a future one, and from what Morrison told us, it doesn't look like it. We asked him if there's demand for a diesel Power Wagon, and he said there's always a little bit, but there hasn't been enough to bring it to market. He also said that demand has actually decreased lately, and he attributed that to low fuel prices right now. So if you really want a compression-ignition Power Wagon, you'd better hope gas prices spike in the near-ish future. Related Video:

Maxwell RHEV Prototype First Drive Review | More than meets the eye

The Maxwell RHEV looks just like any small business' panel van, sporting large vinyl graphics and unassuming steel wheels. You'd have no idea that the co-founders of the startup based out of Seattle had grafted a salvaged Voltec powertrain from a junkyard Chevy Volt into this Ram ProMaster. Somewhere, a battery pack lurks. Maxwell's co-founders, CEO Max Pfeiffer and engineer Trey Camp, open the cargo area to reveal a completely unaltered space. Both are ex-Tesla employees with a long fascination for the #vanlife movement – that their interests intersected in a hybrid cargo van isn't surprising once you start talking to them. This is their first vehicle, a salvaged ProMaster sidelined with a blown 3.6-liter Pentastar, and it's both their prototype and the only Maxwell in existence right now. That said, the company is building a low-roof version for a customer, which will be lighter, have less aero drag and therefore be more efficient. The company is just emerging from a stealth startup mode, and while their backstory is fascinating, I'm still wondering where the Volt's 18.4 kWh battery pack is. "There's nothing in the back ... we're able to get the battery underneath the floor, in the center," Pfeiffer says. Ducking my head under the side reveals, sure enough, a little underside blister that contains the battery, tucked up neatly. The other changes to the RHEV – short for Range-extended Hybrid Electric Vehicle – are minimal. He pops the hood. There are some rough edges, but the 1.5-liter, 101-horsepower engine and 48-kW motor fit comfortably on custom engine mounts and with re-routed exhaust, behind a fascia that improves aero and houses the charge port. Custom axles send power to unaltered Ram hubs and brakes. "This version, it's a little bit prototype-y," Pfeiffer says. "We've had more time to work with the CAD [computer-aided design, engineering drawings] we were able to get from GM and Chrysler, and we've done a better job packaging for production." GM already spent billions on the Voltec and its controlling software, and Maxwell can happily ride those coattails. Despite the help GM has lent Maxwell, there are no official ties. An emulator sends spoofed signals to the Ram instruments, which have a new custom-printed face. The Ram's body control module is left alone. For powertrain faults, Maxwell says the vehicle can theoretically be serviced by any Chevy dealer, and any issue with the rest of the vehicle can be handled by a Ram service shop.
