GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.

Recharge Wrap-up: Volt makes up third of Quebec Chevy dealerships sales, Tesla seeks Aussie talent

A Chevrolet dealership in Quebec has had the Volt make up 35 percent of its sales so far this year. Bourgeois Chevrolet in Rawdon, Quebec received recognition for the feat at the 2014 Electric Vehicle Conference, where it won the award for Leading Plug-in Hybrid Electric Vehicle Dealership. To sell that many, Bourgeois Chevrolet had to import used Volts from the US, and keeps about 50 units on the lot in various configurations. The conference also saw Park Avenue Nissan of Brossard, Quebec win the Leading Battery Electric Vehicle Dealership Award, and Loch Lomond Mitsubishi of Saint John, New Brunswick receive the award for Electric Vehicle Dealership Inspiration.

Ford, General Motors and Toyota have announced that they will shut down their Australian factories, leaving behind a lot of unused talent. Tesla recently held a "Recruiting Open House" in Melbourne for engineers to fill positions at its plant in Fremont, CA, where they will be paired with other Aussie engineers already on staff.

Valeo recently showed an electric turbo it plans to supply to an unnamed automaker at a fuel economy showcase event at the EPA's National Vehicle Emissions and Fuel Lab. Electric turbochargers have the advantage of greatly reduced lag when compared to exhaust-driven turbos. They also work well when paired with cylinder deactivation, providing a much-needed boost when driving on a grade, which can help reduce the need for cylinders to reactivate. Independence from the exhaust system also makes it easier to package the turbocharger wherever there is room. Read more from Navigant Research. US crude oil futures have dropped to their lowest in more than two years. Saudi Arabia cut oil costs for the US and raised them for Europe and Asia as the US has increased output. On November 3, US crude futures fell as much as 2.2 percent in New York. West Texas Intermediate closed at $78.78, the lowest since June 2012. Brent crude slipped $1.08 to $84.78 a barrel.

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.
