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.

Fiat Panda by M-Sport a one-of-a-kind rally car

English racing and engineering firm M-Sport is probably best known for the Bentley Continental GT3 endurance racer and the Ford Fiesta R5 customer rally car. Since building the first of 294 Fiesta R5 Mk. I cars in 2013, the fleet of pint-sized competitors has won a total of more than 950 races. So when a longstanding M-Sport customer asked the company to do something special with a clapped-out, 1990s-era Fiat Panda that would retain the car's Panda-ness but also make it a stonking rally car, M-Sport decided to combine the Italian with the Anglo-American. The result is the Panda by M-Sport, a widened Panda bodyshell lowered atop a Fiesta R5 chassis and engine. Otherwise known as Panda'monium. Or Pandiesta, if you're tipsy. Just fitting the skinny Fiat over the tube-frame chassis meant widening the Panda's body shell by 14.2 inches; that slick grille is actually made of two Panda grilles to gain the required width. That surgery helps maintain the original Panda's silhouette, but more was needed to slide the Fiesta's wider track underneath. More latitudinal stretch was provided by the box-section wheel arches that, up front, flow into a front bumper that is half snowplow. In the longitudinal direction, the Pandiesta's wheelbase is 12.6 inches longer than that of the stock Panda. The Ford's 1.6-liter EcoBoost four-cylinder lives under the hood. It sends nearly 300 horsepower and 332 pound-feet of torque to four Pirelli P Zeros through a five-speed sequential transmission and two custom differentials. The new rear diffuser and single, central exhaust convey the seriousness of the endeavor. Hand-embossed lettering spells "PANDA 4x4" on the rear hatch in case anyone has questions about this having as much capability as the standard Panda 4x4. The interior is all Fiesta R5 save for the Panda-mimicking instrument panel and the co-driver's footrest. The latter is also inscribed with the word "PANDA." Despite the license plate, there's no question of street legality here, or rather illegality. M-Sport says the Panda'monium is ready to do any special stage on tarmac or gravel. Seems this is also the car that launches a new division for customer creations called MS-SV, which is M-Sport Special Vehicles. You can watch M-Sport owner Malcom Wilson take you on tour of the Panda by M-Sport in the video at top, and check out what the finished product can do on a track here.  Related Video: This content is hosted by a third party.

What an Atlas-based Ford F-150 might look like

Just ahead of January's Detroit Auto Show, surprising rumors pegged Ford as revealing some sort of F-150 concept, perhaps as a hurried effort to deflate some of the buzz building around General Motors' new Chevrolet Silverado and GMC Sierra twins, which were also making their auto show debut. Those rumblings turned out to be true, as Ford rolled into the Motor City with its Atlas concept (inset, right), touting the truck's bold styling as a precursor to the next-generation F-Series.
The show truck featured all kinds of clever details, including active wheel shutters and a front air dam that raised and lowered to improve aerodynamics while preserving off-road ability. It also had a genuinely snarly face. And it's that pugnacious snout that may well be on its way to production. The good folks at TopSpeed have worked up the plausible-looking artist's rendering above by cross-referencing the Atlas concept with what little has been revealed from recent spy shots. The look is toned-down pretty dramatically from the concept truck, but its Atlas roots are clear, with a massive three-bar grille and bracket-shaped headlamps hiding a next-generation EcoBoost engine. In the rendering, the show truck's deeply contoured hood and roofline have been ditched and larger, more traditional side mirrors have been fitted - all likely concessions in the move to production sheetmetal.
While Ford has yet to officially announce when it will unveil the 2015 F-150, all signs point to next year's Detroit Auto Show - one year after the Atlas shrugged off GM's new pickups.
