Chevy says not to look at the 2019 Silverado's fuel economy rating

The 2019 Chevy Silverado is hitting dealerships soon, and one of the most notable changes for the new full-size pickup is the addition of a 2.7-liter turbocharged inline-four. The engine replaces the naturally-aspirated 4.3-liter V6 in volume consumer models like the Silverado LT and promises more power, less weight and — most importantly — better fuel economy. The thing is, the gains in efficiency haven't been as dramatic as some might have hoped, especially when stacked up against competitors from Ford and Ram. As Automotive News reports, GM's response is a little murky. First, let's talk numbers. We're pulling all figures from FuelEconomy.gov, the official U.S. government source for fuel ratings. Fuel economy numbers on trucks vary greatly based on a number of factors. Bed and cab configuration play a part, but so does a four-wheel-drive system. You also have to factor in tires, transmissions, rear-axle gearing, hybrid systems and cylinder deactivation. Things like that can make the difference between best- and worst-in-class. The EPA's website doesn't give enough information a lot of the time, so there's really no easy way to compare apples-to-apples. First, take a look at the ratings for the 2019 Silverado. A 2.7-liter model with two-wheel drive is rated 20 city, 23 highway and 21 combined. That's both better and worse than a two-wheel drive 2018 Silverado with the 4.3-liter V6 (18 city, 24 highway and 20 combined). The updated 2019 Silverado with a 4.3-liter V6 has yet to be rated. With less weight and a smaller engine, many hoped Chevy would make bigger gains. It's unusual to see any decrease in a fuel economy metric these days. GM says that it's not done tuning the new 2.7-liter engine, so fuel economy could theoretically increase. Expanding further, a V8-powered 2019 Silverado (17 city, 24 highway and 19 combined) actually gets better highway fuel economy than a turbocharged four-cylinder powered truck in certain configurations, even if the latter has a better overall average. But that's only with two-wheel drive, the 8-speed transmission and cylinder deactivation. A Silverado with the 5.3-liter V8 and a 6-speed automatic is rated at 15 city, 22 highway and 17 combined. The biggest issue with the Silverado 2.7-liter doesn't come from within GM itself but from Ford and Ram. GM cites the Ford F-150 with the 3.3-liter V6 and the Ram 1500 with the 3.6-liter V6 as the closest competitors to its new 2.7-liter inline-four.

Ford GT gets sexy shape and EcoBoost power [w/videos]

American automakers make vehicles of all shapes and sizes, but the one thing they almost invariably share in common is their front-engine layout. Niche offerings from the likes of SSC, Saleen and Vector (and the almost anecdotal Pontiac Fiero) aside, the most notable exception has been the Ford GT. And now it's back. Launched on the floor of the 2015 Detroit Auto Show, the new Ford GT picks up where the last one left off the better part of a decade ago – similarly taking its cues from the original, Le Mans-winning GT40, but in a less retro, more modern form. Instead of the atmospheric V8 in the original or the supercharged one in the retro revival, the new GT packs a 3.5-liter twin-turbo V6 nestled in the middle of its wheelbase and driving "more than 600 horsepower" to the rear wheels. Although Ford hasn't revealed the specific output or performance figures, it says the engine – derived from its Daytona Prototype unit and mated to a seven-speed DCT – is its most powerful production EcoBoost ever. Fortunately it's got carbon-ceramic brakes to keep it all in check, packed into 20-inch wheels wearing Michelin Pilot Super Sport Cup 2 rubber. The discs aren't all that's made from carbon on the new Ford GT, though: it's built around a carbon monocoque with structural carbon-fiber body panels, but with aluminum sub-frames front and back. Ford designed the new GT with a narrower canopy than its predecessors, cutting the frontal aerodynamic profile and tapering towards the back. It's also equipped with active aero elements including an active rear wing. Upwards swinging doors ought to make ingress and egress easier to and from the cockpit that's fitted with fixed seats, adjustable pedals and F1-style steering wheel and a fully digital instrument cluster. The new GT is set to enter production next year to celebrate the 50th anniversary of the GT40's famous 1-2-3 finish at the 1966 running of the 24 Hours of Le Mans. By the time it does, we're sure Ford will let us know just how fast America's newest supercar will be.

Toyota, Ford decide to end hybrid collaboration before it starts

Not all so-called Memorandum of Understanding pacts end in actual collaborations. For instance, after a two-year "feasibility study," Toyota and Ford have just announced that they will not be developing hybrid systems for use in light trucks and SUVs as previously planned, and the two automakers will instead continue to develop their own hybrid technology independently.
The would-be collaboration was first announced in August of 2011, and would have seen a rear-wheel-drive hybrid platform that would "improve the efficiency of trucks and SUVs while still allowing them to be driven in the way customers expect," according to our initial post on the topic.
Keep in mind that this announcement isn't to say we shouldn't expect hybrid pickups and SUVs from the two automakers, but that they probably aren't coming very soon - Ford says it will have a system "before the end of this decade" and we haven't heard much from Toyota on the hybrid truck front since the 2008 A-BAT Concept (pictured above) - and that they will not share any components between them (and they never have, for what it's worth).
