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.

Ford F-450 claims best-in-class towing, company abandons practice of removing items to boost payload number

The ongoing heavy-duty truck battle between Ford and Ram is showing no signs of slowing down. The Blue Oval is trying to remove at least one point of contention between the two brands by testing its 2015 F-450 Super Duty using the Society of Automotive Engineers J2807 towing standard, which Ram also uses. In the new evaluation, the F-450 is rated at a max towing capacity of 31,200 pounds. That's an identical amount as under Ford's own, previous test.
"We leave no doubt with customers that the F-450 pickup truck has best-in-class towing of 31,200 pounds - whether tested using our own internal towing standards or SAE J2807," said Raj Nair, Ford group vice president for Global Product Development, in the company's release.
At the same time, Ford is also changing how it calculates the F-450's payload. Instead of using its minimum curb weight as before, the brand is now using the truck's base curb weight. The revision lowers the pickup's rating to 5,300 pounds, compared to 5,450 pounds previously. The company said in its announcement that the reason for this is "aligning its payload rating practices with other manufacturers to make it easier for customers to compare vehicles." General Motors made a similar switch for its pickups in August.

The EPA has alleged that FCA installed undisclosed emissions software in about 100k Ram and Jeep diesel models [UPDATE]

Update: The text has been updated with official information from the EPA given in a press release and a conference call. Although an initial report from Reuters said the EPA will accuse Ram and Jeep of using emissions defeat devices today, that isn't quite the case. In a press release and a conference call, the EPA stated that the notice of violation sent to FCA is for the installation of eight undisclosed auxiliary emissions control devices on 2014 to 2016 Jeep Grand Cherokee and Ram 1500 models with the 3.0-liter turbodiesel V6. The violation applies to about 104,000 vehicles in total. The agency also explained that auxiliary emissions controls on vehicles are not necessarily illegal, but installing them without disclosing them to the EPA when having the vehicle certified is. Though this initial notice of violation is for installing undisclosed software, the EPA may soon also classify these emissions devices as defeat devices, as it did with the software Volkswagen used. Depending on the outcome of the investigation, there could be fines of up nearly $45,000 per vehicle involved in the notice of violation. The agency revealed that the software alters how the emissions system performs in certain situations. In controlled testing, the vehicles are compliant, but in conditions such as high speed operation, the EPA found the vehicles would produce much higher levels of NOx emissions. The EPA is continuing to investigate, and is waiting for FCA to explain why these emissions control devices are not cheating or defeat devices. In an official statement, FCA stated it is looking forward to explaining that the software does not constitute a defeat device, and has also proposed software updates to achieve compliance. During the conference call, EPA representatives also noted that the vehicles are still safe and legal to be driven, and that owners do not need to take any action yet regarding their cars. It should be noted there is no stop-sale on current models at this time. Additionally, 2017 versions of the 3.0-liter diesel FCA vehicles have not been emissions certified yet.
