Leaked GM document shows GMC Sierra I6 diesel is more powerful than F-150's

GM told us earlier this year that the 2019 GMC Sierra would be getting a 3.0-liter I6 diesel option, but it never mentioned power or fuel economy figures. Hold the phone though, because a leaked GM Canada document just showed up online that lists out the details we've been waiting for. Originally published by TFL Truck, the 3.0-liter oil-burner supposedly makes 282 horsepower and 450 pound-feet of torque. For those who are counting, that's more than the Ford F-150's 250 horsepower and 440 pound-feet from its 3.0-liter diesel. It soundly bests the 240 horsepower and 420 pound-feet of torque from Ram's 3.0-liter diesel as well. Fuel economy is another story, though. The promotional material states that it will get 28 mpg on the highway, which is 2 mpg short of the F-150's 30 mpg — mind you, it's only capable of that magical 30 mpg figure in rear-wheel drive form. There's another caveat here, too; these are numbers for Canada, so they're not exactly finalized EPA figures. However, we wouldn't expect drastic differences between the two when the American numbers come out. The leaked documents also state the diesel Sierra will be capable of towing 7,800 pounds. That number seems remarkably low when compared to the F-150, which can tow up to 11,400 pounds with its diesel. Extra power and torque would have us assume that GM could get even better numbers than Ford, so we're going to hold our final judgment for official word. A 10-speed automatic will do the shifting on the diesel, just like on the 6.2-liter V8. Since the Chevy Silverado is also expected to get this engine, we can assume the figures would be almost, if not identical, to those we see here. We recently drove the 2019 Sierra and Silverado without the diesel engines, so go check those reviews out if you'd like to know more of our thoughts on the redesigned GM trucks. Related video:

Cruze Diesel Road Trip reveals the good and bad, but no ugly

Most of us have strong opinions on diesel-powered cars based on our perceptions of and experience with them. I used to thoroughly dislike oil burners for their noise, smoke and lackluster performance, and the fact that they ran on greasy, smelly stuff that was more expensive than gasoline, could be hard to find and was nasty to get on your hands when refueling. Those negatives, for me, trumped diesel's major positives of big torque for strong acceleration and better fuel economy. Are any of those knocks on diesel still valid today? I'm not talking semis, which continue to annoy me when their operators for some reason almost never shut them down. At any busy truck stop, the air seems always filled with the sound – and sometimes smell – of dozens of big-rig diesels idling endlessly and mindlessly. Or diesel heavy-duty pickups. Those muscular workhorses are far more refined than they once were and burn much less fuel than their gasoline counterparts. But good luck arriving home late at night, or departing early morning, without waking your housemates and neighbors with their clattery racket. No, I'm talking diesel-powered passenger cars, which account for more than half the market in Europe (diesel fuel is cheaper there) yet still barely bump the sales charts in North America. Diesel fuel remains more expensive here, too few stations carry it, and too many Americans remember when diesel cars were noisy, smelly slugs. Also, US emissions requirements make them substantially more expensive to certify, and therefore to buy. But put aside (if you can) higher vehicle purchase and fuel prices, and today's diesel cars can be delightful to drive while delivering much better fuel efficiency than gas-powered versions. So far in the US, all except Chevrolet's compact Cruze Diesel come from German brands, and all are amazingly quiet, visually clean (no smoke) and can be torquey-fun to drive. When a GM Powertrain engineering team set out to modify a tried-and-true GM of Europe turbodiesel four for North American Chevy Cruze compacts, says assistant chief engineer Mike Siegrist, it had a clear target in mind: the Volkswagen Jetta TDI 2.0-liter diesel. And they'll tell you that they beat it in nearly every way. "I believe we have a superior product," he says. "It's powerful, efficient and clean, and it will change perceptions of what a diesel car can be." The 2.0L Cruze turbodiesel pumps out 151 SAE certified horses and 264 pound-feet of torque (at just 2,000 rpm) vs.

Recharge Wrap-up: EV torque secrets, UC Davis maps future of biofuels

A UC Davis white paper maps out "Three Routes Forward for Biofuels," balancing investment risk with carbon benefits. The first option is "incremental," in which we tinker with the existing biofuel manufacturing infrastructure for small improvements over time. The "transitional" plan suggests integrating cellulosic production and other innovations with existing operations. The third route, called "leapfrogging," would mean building refineries based on new technology such as cellulosic and algae-based biofuels. The paper suggests ways the US could use these three routes together in different areas, and predicts the payoffs in terms of carbon emissions could be significant if the right people are willing to risk the capital. After all, financial advisers are always telling investors to diversify their portfolios to manage risk and rewards in the same way.

The seventh round of the inaugural all-electric race season, which was moved from Los Angeles to the streets of Long Beach, will offer fans free grandstand and general admission. The race, which takes place on April 5, 2015, will use a 1.6-mile portion of IndyCar's Grand Prix of Long Beach. Read more at LA Times. Polaris is now offering its 2015 GEM electric vehicles, including the new street-legal eM1400 LSV. The passenger and utility vehicles come in two- to six-passenger configurations, many of which are street legal on roads with posted speed limits of up to 35 miles per hour. The eM1400 LSV utility vehicle seats two, offers 1,250 pounds of payload, 1,250 pounds of towing capacity, a top speed of 25 mph and a range of up to 45 miles. Its on-board charger plugs into any standard 110-volt outlet. Read more at Hybrid Cars and check out all the different configurations yourself at the Polaris website. In EVs, more torque does not always equal faster. Green Car Reports found this out when driving the Fiat 500e (with 147 pound-feet) against the similarly weighted Chevrolet Spark EV (with 400 pound-feet). The secret is, at least in part, in the gearing. The Fiat has a 9.6:1 reduction gear, making it quicker at lower speeds despite having far less available torque, while the Chevy uses a 3:1 ratio. The trade-off though, is in top speed. Furthermore, Chevy electronically limits the torque delivery at low speeds, as 400 pound-feet is a lot of launch for the little Spark EV to handle.
