GM natural gas-powered vans recalled due to possible leak

General Motors is recalling almost 3,200 of its compressed-natural-gas powered utility vans because of possible leaks. GM and the National Highway Traffic Safety Administration (NHTSA) released a notice last week saying that 3,196 Chevrolet Express and GMC Savana CNG vans are on recall, though no accidents have been reported due to the possible issue. The recall is specifically for vans for model years ranging from 2011 to 2014. The recall stems from a potential leak from the compressed natural gas high-pressure regulator, and such a leak could cause a fire or explosion. GM will replace the vehicles' high-pressure regulator in order to fix the problem, will do it free of charge and is instructing owners to contact Chevrolet or GMC customer service to arrange for the parts replacement. Utility vehicle makers like General Motors have pushed for fleet sales of CNG-powered vans and trucks for the past few years and have touted them for their cheaper refueling costs relative to standard gasoline, not to mention the fact that natural gas can be readily sourced from throughout North America (thanks, fracking). According to CNGPrices.com, compressed natural gas sells for about $2.22 a gallon, on average, while the AAA is pegging the average price of gas at $3.34 a gallon. NHTSA has posted information on the recall here. Featured Gallery News Source: NHTSA via Reuters Green Chevrolet GM GMC Natural Gas Vehicles CNG gmc savana

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

Weekly Recap: Bentley Bentayga leads luxury SUV charge at Frankfurt

The Bentley Bentayga is launching a new era of ultra high-end sport utility vehicles that will see luxury makers vie for the world's richest and most exclusive customers. The Bentayga is Bentley's first SUV, and it will formally debut next week at the Frankfurt Motor Show. It's loaded with Bentley's best technology and features, led by a 600-horsepower W12 engine. The mission is simple: stop giving up sales to other companies by not having an SUV in its portfolio. "It creates an entirely new category of ultra-luxury SUV, where there are currently few rivals," IHS Automotive analyst Ian Fletcher said in a report. But Bentley and the Bentayga will soon face stiff competition. Archrival Rolls-Royce will produce its own crossover to be built in England, though timing is unclear. Lamborghini has approved plans for a ute that will be assembled in Italy and launch in 2018. Even the sportier British brands are getting into the market. Aston Martin will make a crossover version of the DBX concept shown earlier this year in Geneva, and Jaguar is launching the F-Pace crossover, which will debut in Frankfurt. These new entries will invigorate a segment that's comprised of the Mercedes G63 AMG and the Land Rover Range Rover SV Autobiography, and Bentley is poised to grab a large share of it, Fletcher noted. IHS forecasts Bentayga sales could hit 3,000 units per year in 2017 and 2018, pushing total Bentley sales to more than 10,000 in the next few years. The vehicle will also get plug-in hybrid and diesel variants to widen its reach. The Bentayga is a sales grab, for sure, but Bentley took care to ensure the SUV remained true to the brand. It's laden with the top-shelf wood, leather, and metal, and it comes standard with an expansive panoramic glass roof. It also has intelligent features like electronic night vision and an optional responsive off-road system that can be configured to adapt to eight different settings. It's a different kind of Bentley, but it's a harbinger of things to come for the world's richest luxury makers.

The car promises 10-percent gains in fuel efficiency, though actual figures – and even powertrain specifics – were not revealed. We estimate that could mean about 56 miles per gallon in city driving and 53 on the highway.
