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.

Ram recalling 131,000 heavy duty trucks over fire hazard

For a little over a year, Ram has been investigating an issue with a number of heavy duty trucks from the 2021 model year that have experienced engine bay fires. For some reason, even when the engine is off, the solid-state intake heater relay in Ram trucks fitted with the 6.7-liter Cummins turbodiesel can suffer a short and catch fire. In March of this year, the company planned to recall about 20,000 vehicles in the U.S. and Canada when it thought the problem was limited to trucks with unprotected relays. In May, Ram discovered the issue occurring even in trucks with protected relays. Now Ram is preparing to recall 131,177 trucks from the 2021 and 2022 model years. The models in question are:  2021-2022 Ram 2500 (DJ) pickups built between August 3, 2020 and October 8, 2021 (67,597 units) 2021-2022 Ram 3500 (D2) pickups built between August 5, 2020 and October 8, 2021 (39,324 units) 2021-2022 Ram 3500 Chassis Cabs (DD) built between August 12, 2020 and October 7, 2021 (7,317 units) 2021-2022 Ram 4500/5500 (DP) Chassis Cabs built between November 13, 2020 and October 8, 2021 (16,939 units) Ram says it is aware of about 10 engine bay fires, but no accidents nor injuries due to the fires. The bigger issue for now is that Fiat Chrysler engineers working with the component supplier still haven't been able to find a root cause for the fires. Until they can nail down a cause, Ram recommends parking affected models outside, away from structures and other vehicles.   The pickup maker expects to begin mailing letters to owners on December 3, the same day it informs dealers of the fix for the issue. Owners with questions can call the Stellantis customer service line at 1-800-853-1403, the automaker's internal code for the recall being Y76. Or they can contact the National Highway Traffic Safety Administration (NHTSA) Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153). Or go to www.nhtsa.gov. The NHTSA campaign number is 21V798 Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Best car infotainment systems: From UConnect to MBUX, these are our favorites

Declaring one infotainment system the best over any other is an inherently subjective matter. You can look at quantitative testing for things like input response time and various screen load times, but ask a room full of people that have tried all car infotainment systems what their favorite is, and you’re likely to get a lot of different responses. For the most part, the various infotainment systems available all share a similar purpose. They aim to help the driver get where they're going with navigation, play their favorite tunes via all sorts of media playback options and allow folks to stay connected with others via phone connectivity. Of course, most go way beyond the basics these days and offer features like streaming services, in-car performance data and much more. Unique features are aplenty when you start diving through menus, but how they go about their most important tasks vary widely. Some of our editors prefer systems that are exclusively touch-based and chock full of boundary-pushing features. Others may prefer a back-to-basics non-touch system that is navigable via a scroll wheel. You can compare it to the phone operating system wars. Just like some prefer Android phones over iPhones, we all have our own opinions for what makes up the best infotainment interface. All that said, our combined experience tells us that a number of infotainment systems are at least better than the rest. WeÂ’ve narrowed it down to five total systems in their own subcategories that stand out to us. Read on below to see our picks, and feel free to make your own arguments in the comments. Best infotainment overall: UConnect 5, various Stellantis products Ram 1500 Uconnect Infotainment System Review If thereÂ’s one infotainment system that all of us agree is excellent, itÂ’s UConnect. It has numerous qualities that make it great, but above all else, UConnect is simple and straightforward to use. Ease of operation is one of the most (if not the single most) vital parts of any infotainment system interface. If youÂ’re expected to be able to tap away on a touchscreen while driving and still pay attention to the road, a complex infotainment system is going to remove your attention from the number one task at hand: driving. UConnect uses a simple interface that puts all of your key functions in a clearly-represented row on the bottom of the screen. Tap any of them, and it instantly pulls up that menu.
