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.

Weekly Recap: Lamborghini to build SUV

Finally, Lamborghini will build a sport utility vehicle. The Italian supercar maker confirmed this week that it will launch a luxury SUV in 2018. It will be built at Lamborghini's soon-to-expand factory in Sant'Agata Bolognese in Italy, and will double the company's current sales volume. Lamborghini did not announce a name for the vehicle or other details, but noted a concept version, the Urus, was displayed at the Beijing motor show in 2012. It will be sold around the world, but it's expected to be a critical offering in the United States, China, and the Middle East. The automaker projects the SUV will sell about 3,000 units per year, and it will be the third product in Lamborghini's portfolio. It currently sells the Huracan and Aventador supercars. "The introduction of a third model line endorses the stable and sustainable growth of the company and signifies for us the beginning of a new era," Lamborghini chief executive Stephan Winkelmann said in a statement. The project is also a boon for Italy, which will get 500 new jobs in the Emilia Romagna region as Lamborghini's factory will nearly double in size. Ian Fletcher, principal analyst for IHS Automotive, said the SUV will position Lamborghini for future growth. "It could well also bring new customers to the brand [who] may find the dramatic styling of Lamborghini products appealing, but find its typical sports cars restrictive," he said. "If it is a success, the SUV could be a catalyst to Lamborghini broadening its portfolio further." OTHER NEWS & NOTES GM invests in Chevy Camaro factory General Motors is investing $175 million to upgrade its factory in Lansing, MI, to build the 2016 Chevy Camaro. The investment will pay for new tooling and equipment. The improvements include three new paint systems and two new robotic framers. GM will add a second shift at the factory to build the Camaro, resulting in 500 jobs. The automaker had dropped the plant to one shift last year amid slow sales for its products, the Cadillac ATS and CTS. GM is spending $5.4 billion over the next three years to upgrade its US facilities. Last week, GM announced plans to spend $439 million to build a new paint shop for the Chevy Corvette. While the Camaro and Corvette plant improvements are intriguing to enthusiasts, GM also confirmed this week that it is investing $1.2 billion in its Fort Wayne (IN) factory that builds trucks.

2020 Chevy Silverado, GMC Sierra recalled due to faulty brake component

General Motors is recalling 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups to fix a defect in the trucks' brake system. Certain Silverado and Sierra pickups were produced with brake-caliper bolts that were not heat-treated. Without heat-treating, the bolts are weaker than they should be, and there is a risk that they could fail, which would affect the trucks' braking performance, possibly leading to a crash. In total, 20,352 vehicles are affected. Owners of affected trucks will be contacted by GM. Dealers will inspect the bolts and replace those that are defective. Related Video:
