CNG Chevy Impala launch delay grows to a year

The 2015 Chevrolet Impala Bi-Fuel was announced in Washington D.C. in late 2013 by Dan Akerson and was supposed to be on sale by the summer of 2014. Capable of running on gasoline and compressed natural gas, the sedan was said to offer a novel solution at a time when gas prices were high. The vehicles still haven't arrived at dealers, though, and according to Automotive News, a quality issue has set back the launch even a few months more. Using a modified 3.6-liter V6 with hardened valves and valve seats, the Bi-Fuel Impala has separate tanks for gasoline and CNG that it can switch between on the fly. When running on the cheaper natural gas, the sedan was estimated to get 19 miles per gallon in the city and offer 150 miles of range, and the total driving distance was predicted at around 500 miles. The base price was set at $38,210, after the $825 destination charge. The only other major tradeoff was a smaller trunk to accommodate the extra fuel. However, the first shipments of the bi-fuel models now aren't expected until mid-July – about a year later than the scheduled launch. A memo to dealers obtained by Automotive News said the sedan "has been delayed by a second quality hold" to look at the CNG system. The exact details surrounding this problem haven't been released. "We have identified a solution to the delay and are working hard to implement it within the next few months," General Motors spokesperson Chad Lyons said to Automotive News. Around 200 Bi-Fuel Impalas have been made, but none are yet in the hands of customers. Dealers should be able to order 2016 model year examples starting in the third quarter of this year.

2017 Chevy Corvette Grand Sport spotters guide

The 2017 Corvette Grand Sport is a mix of regular Stingray and steroidal Z06. Unveiled at the 2016 Geneva Motor Show, this tweener 'Vette will go on sale this summer. If you need a refresher, click here for the details and official press release. We sat down with Chief Engineer Tadge Juecter in Switzerland to explain the differences between the Grand Sport and the rest of the Corvette lineup. <p>Your browser does not support iframes.</p> Stingray Hood The Grand Sport comes with the LT1 V8 (and 460 horsepower) instead of the supercharged LT4 in the Z06. That means the Grand Sport gets the lower Stingray hood, absent the power bulge. The Grand Sport also weighs less than the Z06. As such, the Grand Sport's springs and anti-roll bars are different to accommodate the lighter nose. "Mainly it's the weight distribution that changes," explains Juecter, "It's a custom tune around the obvious standard components." Grand Sport Wheels, Z06 Brakes In the sixth-generation Corvette, the Grand Sport came with a Z06-style body but kept the standard Vette's steel structure. With every version of the C7 built on an aluminum backbone, the Grand Sport has almost the same structure as the Z06. That means the Grand Sport can handle all the track-ready goodness like Z06 brakes and the optional Z07 package that adds carbon-ceramic disks and Michelin Pilot Sport 2 Cup tires. Except the Grand Sport comes without the max-downforce add-ons of the Z07-packaged Z06, because it doesn't need them. What you can't get on the Z06, though, is the unique Grand Sport wheel design, which comes in five different finishes. Stingray Brake Lights, Interior The dead giveaway for the Grand Sport is the hash marks on the front fenders which come in six different colors. Another way to spot the Grand Sport is the taillights, which use the Stingray's red lenses instead of the blacked-out Z06's lights. Z06 body plus taillights equals Grand Sport. Got that? The Grand Sport also comes with body-color rear fender vents, which are black on the Z06. And the Grand Sport's interior is based on the Stingray except the Collector Edition, which has unique blue accents.

GM seatbelt recall affects over 1m Silverados and Sierras

The Basics: General Motors will recall 895,232 examples of the 2014-2015 Chevrolet Silverado and GMC Sierra 1500 pickups in the US. The campaign will also affect the trucks in markets worldwide, and the total number the company will recall is 1,037,982. The Problem: A steel cable connects the seatbelt to the vehicle, but over time repeated bending can cause the part to fatigue and separate. Injuries/Deaths: None reported. The Fix: Dealers will enlarge the side shield opening and install a pusher bracket on the tensioner. Technicians will also replace the entire tensioner assembly if necessary. If You Own One: GM will contact owners about the recall. The company hasn't said when those notifications would begin. More Information: There are still about 3,000 new examples of these older pickups at dealerships. Until mechanics fix the problem, these vehicles are subject to a stop-sale. Similar problems have affected the General's vehicles in the past. In 2015, the company recalled over 400,000 units of the 2011-2012 Chevrolet Malibu for fatiguing cables. It also hit over a million Lambda platform crossovers in 2014. GM Recalling Certain 2014-15 Pickups to Repair Seat Belts DETROIT – GM is voluntarily recalling 895,232 model year 2014-15 Chevrolet Silverado and GMC Sierra 1500 pickups in the United States because the flexible steel cable that connects the seat belt to the vehicle can fatigue and separate over time as a result of the driver repeatedly bending the cable when entering the seat. This issue was discovered through warranty data, and there have been no reports of crashes, injuries or fatalities related to this issue. For trucks in the field, dealers will enlarge the side shield opening, install a pusher bracket on the tensioner, and if necessary, replace the tensioner assembly. The recall in the United States includes a stop-sale of approximately 3,000 new 2014 and 2015 model year pickups still on dealer lots. Dealers will repair the vehicles prior to delivering them to customers. Customers will be notified by General Motors. They also can look up their vehicle identification number (VIN) at either https://vinrcl.safercar.gov/vin/ website or at https://my.gm.com/web/portal/ownercenter to see if their vehicle is part of the recall. GM also will voluntarily recall and repair these models in other countries where they are sold, including Canada, Mexico, and several countries in Latin America and the Middle East.
