NHTSA probes 2010 Chevy Tahoe for side airbag issue

After a person was killed in a rollover accident in a 2010 Chevrolet Tahoe in Texas in 2011, the National Highway Traffic Safety Administration is considering whether to conduct a deeper investigation into a potential problem with the model's side airbags. According to the petition filed with the government agency, the SUV's rollover side curtain airbag deployed in the accident, but the design allegedly still allowed some of the occupants in the second- and third-row seats to be ejected from the vehicle. One of them died in the crash. Based on NHTSA's preliminary review, this is the only report of this type of incident happening in a 2007-2015 Tahoe or GMC Yukon. "GM investigated the complaint that is the basis of the petition and found no defect trend," company spokesperson Alan Adler said to The Detroit News, and said the automaker will cooperate with the feds. Still, "a defect petition has been opened to evaluate the issue and make a grant or deny decision," according to NHTSA. Depending on the agency's findings, this could lead to a full investigation and possible recall affecting an estimated 58,000 vehicles. INVESTIGATION Subject : Rollover Side Curtain Air Bags Date Investigation Opened: JUN 11, 2015 Date Investigation Closed: Open NHTSA Action Number: DP15004 Component(s): AIR BAGS All Products Associated with this Investigation Vehicle MakeModelModel Year(s) CHEVROLET TAHOE 2010 CHEVROLET TAHOE HYBRID 2010 Details Manufacturer: General Motors LLC SUMMARY: The Office of Defects Investigation (ODI) has received a petition requesting an investigation of alleged defects that can cause occupant ejections during rollover crashes in certain General Motors vehicles. The petition alleges the defects allow second and third row occupants to be ejected despite the deployment of rollover side curtain air bags. The petition cites a 2011 Texas crash involving a model year 2010 Chevrolet Tahoe, which allegedly resulted in multiple occupants to be ejected. One of the ejected occupants was fatally injured. ODI's preliminary review of its consumer complaint data found no similar reports of occupant ejections on 2007-2015 Chevrolet Tahoe and GMC Yukon vehicles. ODI also reviewed Early Warning Reporting data submitted by General Motors. A defect petition has been opened to evaluate the issue and make a grant or deny decision.

This 450-hp electric Lotus Evora is powered by Tesla and Chevrolet

When someone mentions an electric Lotus, the first thing that comes to mind is the Tesla Roadster, the California-based automaker's first vehicle. That car started life as an Elise before being heavily massaged and adapted by Tesla's engineers. In a similar spirit, the people at Onpoint Dyno are close to finishing Blue Lightning, a track-ready all-electric Lotus Evora. Blue Lightning uses a Tesla drive unit and a Chevrolet Volt battery pack, both mounted in the middle in place of the Evora's 3.5-liter Toyota V6. It's putting down about 450 horsepower at the wheels. The car was built for time attack sessions, so power is fed through custom forged wheels and super sticky Pirelli PZero Trofeo R tires, the same ones found on the last Chevrolet Camaro Z/28. There is a custom digital instrument cluster in place of the Lotus gauges. There's also a regen paddle on the left side of the steering wheel. With a full charge, Blue Lighting should go about 120 miles. While the car runs under its own power, it's only about 90 percent complete. It has no power steering, no firewall in between the seats and the motor and battery pack, no A/C, and a large hole where the shift lever used to be. Other final touches include fine-tuning the brakes and suspension. There is also a custom rear bumper coming that should make it look more like the new Lotus Evora 400. Onpoint Dyno expects the car to hit the track in the next month or so. Related Video:

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises.
