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.

Junkyard Gem: 1987 Chevrolet Turbo Sprint

Fifteen years ago, I wrote my first-ever automotive article under the name Murilee Martin, and it didn't take me long to start writing about one of my favorite automotive subjects: the junkyard. Before I'd refined my system for documenting discarded vehicles, however, I shot a lot of boneyard photos that never got used. For today's Junkyard Gem, I have four shots from early 2007 of one of the rarest turbocharged machines of the 1980s: the Chevrolet Turbo Sprint. The Chevrolet Sprint was really a rebadged Suzuki Cultus, from the pre-Geo era when General Motors sold the Isuzu Gemini as the Chevrolet Spectrum, the Daewoo LeMans as the Pontiac LeMans and the Toyota Corolla as the Chevrolet Nova (soon enough, the Spectrum became a Geo, and the Nova became the Prizm). The second-generation Cultus appeared in 1988, becoming the Geo Metro on our shores the following year. The Turbo Sprint was available for just the last two years of the Sprint's 1985-1988 American sales run, and it appears that just a couple of thousand were sold; if I'd known at the time just how rare they were, I'd have shot more photos of this one at the now-defunct Hayward Pick Your Part. The turbocharged 993cc three-cylinder produced 70 horsepower, 22 better than the naturally-aspirated version. Since the Turbo Sprint weighed just 1,620 pounds (that's about 500 pounds lighter than a barely more powerful '22 Mitsusbishi Mirage), it was plenty of fun to drive. For 1988, the regular Sprint hatchback cost $6,380 while the Turbo Sprint listed at $8,240 (that's about $15,375 and $19,855 today, respectively). Believe it or not, a Turbo Sprint actually raced in the 24 Hours of Lemons 10 years ago, though it didn't end well. This ad is for the regular Cultus, not the Cultus Turbo, but the screaming guitars sound reasonably turbocharged. For the most part, Chevy Sprint marketing was all about cheap purchase price and stingy fuel economy… at a time when gasoline prices were cratering. Related Video:

Recharge Wrap-up: Chevy Volt class action suit proposed, Tesla stock could outperform in 2015

A class action suit has been proposed against General Motors for a steering problem in the Chevrolet Volt. The plaintiffs claim that a defect can cause the steering to freeze intermittently, and that General Motors either knows or should have known about the problem. The case, filed in New Jersey, also claims that defective parts are replaced with the same or similar parts, which are also defective. The plaintiffs say that claims for the 100-plus-member class exceed $5 million. Read more at Law360 or at BigClassAction. Tesla Motors stock (TSLA) has risen after weeks of losses. It gained 5.4 percent during the week ending December 19, when it closed at $219.29 per share. Since then, it rose slightly more, closing at $222.26 on December 24. Morgan Stanley lowered its target price on Tesla stock from $320 to $290, predicting lower sales on the upcoming Model III than expected before, but still called Tesla a good long-term investment. Analysts at CNBC predicted Tesla to be the best performing stock of 2015. Read more at ETF Daily News. Oslo- and New York-based architecture firm Snohetta has designed a zero-emissions house that also charges an electric car. The ZEB Pilot House, built in Larvik, Norway, uses a solar panel on the roof to power the house, which also provides enough excess energy to charge an EV. To make the most of energy most efficiently, the house uses smart technology to use as much energy as it can once it's harvested. This means one can turn on appliances like the washing machine remotely while the sun is at the optimum angle in the sky - perhaps during mid-day when the residents are at work. The house also uses organic materials and is designed to save as much energy as possible. Read more at Wired.
