Ram 1500 bests new F-150 in MT pickup shootout

Ford's 2015 Ford F-150 is a technological tour-de-force, what with its aluminum-intensive construction and its powerful and efficient new 2.7-liter EcoBoost engine option. But now that it's hit the market, it's time to get down to brass tacks and find out how just the latest F-150 actually stands up to its rivals in the hyper-competitive fullsize segment. Motor Trend is among the first to round up the Ford (in Lariat 2.7-liter 4X4 guise here) and put it up against the Ram 1500 Outdoorsman EcoDiesel 4x4 and 5.3-liter-equipped Silverado 1500 LTZ Z71 to find out how Dearborn's new-think truck measures up. The test put the trio through over 1,000 miles of tough driving in California and Arizona in a variety of conditions from just cruising around unladen to hauling a trailer. MT found all three trucks to be competent, but the most praise got heaped on the Ram and the Ford, with the Chevrolet falling a step behind its competitors in many tests. Among the Ford's most-liked features was its 2.7-liter, twin-turbo V6 that helped make the F-150 easily the quickest of the group, with some editors saying the engine felt about the same whether driving around with cargo in the bed or not. There was some minor turbo lag during acceleration while trailering, but that issue affected the Ram, too. The Ram's powertrain was lauded, as well. The EcoDiesel was torquey around town, and the 1500's combination of an eight-speed automatic and air suspension was judged to be the best of the lot. It was the most difficult to get into the bed, though. The Ram also won the fuel economy award by netting 20-miles-per-gallon city and 28-mpg highway in the test to beat its Environmental Protection Agency ratings of 19/27. The Ford's EcoBoost managed 17/22, one mpg off each from the EPA numbers, and using a lot of throttle really depleted its efficiency. As MT notes, however, it would take time for the diesel's mileage savings to pay off at the pump for these two trucks. In the end, the Ram just barely eked out the win, with the title partially earned because of "the Ford's unknown maintenance and aluminum repair costs," according to MT.

Battery Show 2015: Genovation GXE Corvette EV designed for the 'Ring

The Genovation GXE all-electric Corvette has broken cover. At the Battery Show 2015 in Novi, MI, this week, the converted C6 Z06 Corvette that we first heard about back in August was tucked into a booth along the back wall. Don't let the demure location fool you. This is a muscle-y electric vehicle, ready to roar into the limited-run, expensive EV game. The Genovation GXE Corvette can go from 0-60 miles per hour in three seconds and has a top speed of 200 mph. The powertrain was designed and built in the US, and offers over 700 horsepower and over 600 pound-feet or torque. With a near 50/50 weight distribution, this is "a real driver's car," Genovation CEO Andrew Saul told AutoblogGreen. Saul said that the GXE was designed to do two hard laps at Nurburgring thanks to a 44-kWh battery pack uses the same sort of cylindrical 18650 cells that you can find in a Tesla. That translates to about 40-50 miles of fast, on-road driving, Saul said, or 150 miles on the New York City test cycle. That particular test, "simulates low speed urban driving with frequent stops," according to DieselNet. The car also has a 6-kW charger and a six-speed manual transmission and the adjustable regenerative braking levels can be controlled by paddles on the steering wheel. Of course, none of those performance figures have been proven yet because the GXE hasn't had a chance to hit the road. Saul said that it will take another three-to-four weeks to finish the build and then, finally, there will be a few weeks of road testing. This will include a quarter-mile run on a track as well as a trip to Nevada to do a several-mile top speed test. If all of that sounds like something you're interested in, then get ready to open your wallet wide and wait. Saul said that buying one will set you back $330,000 (just $290,000 if you bring your own C6 Z06). Genovation also won't be making all that many. Saul said he expects to put the GXE into limited production of under 200 units, starting off at maybe five or 10 a year.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."
