GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:

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.

Best new convertibles for 2024 and 2025

If you’re here, then youÂ’re already in the right mindset. Convertibles rule, and we have all the best convertibles listed for you further below. Driving around with the top off is an experience you need to live to fall in love with. When the weatherÂ’s right, youÂ’re on a proper bit of road, and the car youÂ’re in is a good one, few automotive experiences can top it. The experience is extra special when you have a musical exhaust note filtering directly into your ears and echoing off the landscape around you. And while rolling the windows down and opening a moonroof can get you part of the way there, it's nothing like feeling the wind wash over you with absolutely no roof overhead. The downsides can be just as harsh as the upsides when youÂ’re in the wrong conditions, though. Convertibles are typically worse to live with in cold climates, and driving around with the top up frequently means you might be subject to more road noise and worse visibility than an equivalent coupe. And when it comes to pure performance, convertibles are inherently compromised from a weight and structural rigidity perspective. All that said, we still think the upsides outweigh the compromises if your number one objective is to simply have fun. ItÂ’s a good thing then that there are a ton of great convertibles for sale these days. And no, the list of possibilities isnÂ’t as long as it used to be. Long-running standbys like the Mercedes-Benz E-Class and C-Class Convertibles are gone (replaced by the one CLE-Class). And so are others like the Audi TT Roadster, Fiat 124 Spider and Nissan Z Roadster. Nevertheless, opportunities abound from the ultra-cheap and fun, to physics-defying supercars and everything else in between. WeÂ’ll give you options for which new convertibles we think are the best below, so read on to find out.   Mazda MX-5 Miata Pros: Lightweight and compact; great engine and transmission combo; one of the most raw and pure driving experiences out thereCons: Not great for tall people; infotainment is dated; tiny trunk Read our Mazda MX-5 Miata Review Miata is always the answer, right? In this case, that rings even more true than usual. In fact, you could stop reading this list right here and go buy a Miata and youÂ’d likely be just as happy driving it around as you would be in any of the more expensive offerings that follow. ThatÂ’s just the magic of the MX-5.
