Driving the C8 Corvette, and previewing GM's electric future | Autoblog Podcast #617

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by West Coast Editor James Riswick and Road Test Editor Zac Palmer. First they dive right in to the experience of driving the 2020 Chevrolet Corvette, followed by their review of the Mercedes-Benz GLE 350. Then they talk about the week's news, beginning with the whole slew of electric vehicles General Motors surprised us with at its EV Day. Next, they discuss the possibility of Porsche building a hybrid 911, as well as news about Ford's electric Transit van making its way to the U.S.. Last, but not least, they take to the mailbag to help a listener pick his next car in the "Spend My Money" segment.

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.

2022 Chevrolet Silverado LT Trail Boss adds 3.0-liter diesel option

Order books just opened for the 2022 Chevrolet Silverado, which, in case you hadn't heard, is almost unchanged compared to the 2021 Silverado. The overhauled Silverado and GMC Sierra that we caught in spy shots several times last year and were expected to launch this year have been delayed. Until that pickup gets here, Chevrolet and GMC will add "Limited" to the names of the Silverado and Sierra. Fleet guides for next year's truck show the official model name as Chevrolet Silverado 1500 LTD. There are a few interesting features coming next year, though, like the Multi-Flex tailgate joining the options list for Silverado HD trucks. GM Authority also reports that the 2022 Silverado LT Trail Boss adds the 3.0-liter oil-burner with 277 horsepower and 460 pound-feet of torque as a third engine option, which should be a big treat for the off-roading crew. Whereas the GMC Sierra AT4 already offers the 3.0-liter diesel, the Silverado LT Trail Boss only offers the 5.3-liter and 6.2-liter V8s, both bolted to GM's ten-speed automatic transmission. Then there's the Custom Trail Boss that adds the 4.3-liter V6 as an option, and it and the 5.3-liter V8 only get 6-speed automatics. At the moment, Silverado trims that offer the Duramax charge a $1,045 for it over the 5.3-liter V8. If that gap holds true for next year, the diesel will just about evenly split the price difference between the LT Trail Boss with the 5.3 and the 6.2.   Elsewhere in the range, Driving.ca said Canadian fleet guides show the 4.3-liter V6 and lower-spec 5.3-liter V8 with Active Fuel Management (AFM) instead of Dynamic Fuel Management (DFM) disappearing from next year's base Silverado WT. To clarify, AFM only shuts off half the cylinders in certain conditions, whereas DFM constantly adjusts how many cylinders are firing all the time. As it stands, that would leave the 2.7-liter turbo four-cylinder as the only engine option. However, those other two mills were the only ones left in the lineup that shift through a six-speed transmission, making it possible that they'll rejoin the options list with at least two more gears to choose from. It's not clear if GM will sell the Limited models alongside the majorly upgraded 2022 Silverado. The automaker did just that a few years ago, selling the previous-gen truck as a Limited trim alongside the then-new, current-gen. It certainly wouldn't be the only company to do so, either.
