Ford lowers MPG ratings on six vehicles

Ford has announced that it will be lowering the fuel economy ratings on a number of its 2013 and 2014 model year vehicles after an error was discovered in the company's internal testing data. The EPA has been notified.
Worryingly for Ford, the vast majority of the vehicles affected are hybrids, including the C-Max, Fusion and MKZ in both hybrid and plug-in varieties (where applicable). Also covered as part of the rerating is the entire lineup of 2014 Fiesta engines, with the exception of the ST, including the turbocharged, three-cylinder EcoBoost.
The C-Max was originally rated at 47/47/47 mpg, but dropped to 43/45/40 last year and now to 40/42/37.

Ford GT racer sounds wicked during testing at Sebring

The Ford GT racecar is still deep in development ahead of a much-anticipated trip to the 24 Hours of Le Mans next year. If the sound in this clip is any indication, the honing of this racecar is going quite well. Like any proper racer, you hear the GT rumbling well before it enters frame, but then the beauty comes into view at Sebring with a massive rear wing and an even bigger diffuser. Rather than an ear-piercing shriek, the 3.5-liter EcoBoost in the GT sounds like a grumbling monster. The previous development video from Ford Performance hints at this angry exhaust note, but it's on full display here. Thankfully race fans around the world get to hear this wonderful noise when the GT hits the track next year. Two of them are competing in the United SportsCar Championship, and two more are in the FIA World Endurance Championship. All of the members of this quartet are also lining up at Le Mans, too. Hearing them making this wonderful growl together should be a major highlight of motorsports in 2016. Related Video:

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.
