GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

2025 GMC Sierra EV rumored to offer a smaller 170-kWh pack as standard

It's kind of wild that you can order a 2024 GMC Sierra EV Denali Edition 1 pickup, yet GMC hasn't released specific figures for battery capacity; maybe that's info you only get after putting down a deposit. Adding to the mystery, the 2025 GMC Sierra EV, already being promoted at the GMC site and which will be available later this year, will add a second battery. GM Authority says the pack in the 2024 truck (that only comes in one trim) is the 204-kWh pack we already know from the GMC Hummer EV. In April, GMC raised the estimated range rating for that pack from 400 miles to 440 miles, upped towing capacity by 500 pounds to 10,000 pounds, and raised max payload capacity by 150 pounds to 1,450 pounds. For 2025, GMA says the the Sierra EV range will add a smaller 170-kWh pack for lower trims.  Trims, you ask? Yes, next year's standard Denali trim will be joined by AT4 and Elevation trims. The AT4 will come with trail-use perks like four-wheel steering, CrabWalk, and two additional inches of ground clearance thanks to 18-inch wheels wrapped in 35-inch all-terrain tires, plus Super Cruise and a spray-on bedliner. Optional features on the AT4 include a DC fast charge upgrade to 350-kW, GMC's MultiPro MidGate, and the 10.2-kW Power Station Pro. The Elevation, typically a lower trim in GMC's vehicle lineups, comes with a power-operated frunk, the MultiPro tailgate, and sits on 18-inch wheels in 33-inch rubber. The Elevation options menu will offer the MultiPro MidGate, Super Cruise, spray-on bedliner, Power Station Pro, and fast charge upgrade. The Denali will come with all of these tech features standard, but sit on 24-inch wheels in 35-inch rubber. New colors will expand the palette from the sole option today, Thunderstorm Gray, to include Deep Ember Tintcoat, Deep Ocean Metallic, Moonlight Matte, Onyx Black, and Summit White. Back to the battery, the 2025 Sierra EV's order guide shows two pack options, an Extended Range and a Max Range, without giving capacity figures. GMA believes this will be a 20-module pack of 170 kWh, powering a range of around 380 to 390 miles. The 2025 trucks reportedly begin heading down lines in early September, starting with the Denali trim, so information should be forthcoming in the not-too-distant. The AT4 and Elevation trims will reach dealerships early next year.

GM recalling 54k Cadillac SRX, HD pickup models

There are more recalls to report General Motors, but these latest actions pertain to newer examples of the Cadillac SRX, Chevrolet Silverado HD and GMC Sierra HD. With so much scrutiny on the company's recall strategy, GM is under increasing pressure to call in defective models more quickly, and it appears to be doing so here.
Here in the US, the automaker is recalling 50,571 Cadillac SRX crossovers from the 2013 model year fitted with the 3.6-liter V6 because the transmission control module programming can cause a three- or four-second lag in acceleration at low speeds. The explanation filed with the National Highway Traffic Safety Administration states, "if the following sequence occurs within two seconds: during an upshift from first to second gear (8-10 mph), the driver then brakes the vehicle to less than 5 mph, and then accelerates again," the delay can occur. According to Automotive News, the recall effects 56,400 vehicles worldwide, and the company is not aware of any crashes caused by the problem. The fix consists of a transmission control module (TCM) reflash.
In a separate recall, GM is repairing 51 Chevrolet Silverado HD and GMC Sierra HD pickups from the 2015 model year in the US. In vehicles with diesel engines and dual fuel tanks, the nuts that connect the fuel pipe to each side of the transfer pump between the tanks may be improperly torqued, which could cause a fuel leak. Obviously, this could be a fire hazard. The remedy is simply tightening the hardware. According to GM spokesperson Alan Adler, there have been no fires actually caused by the potential leak. "Only 21 of the trucks are in customer possession and they can be fixed anytime because there are no parts involved. The others are being fixed at dealerships," Adler said in an email to Autoblog.
