Tesla Models Under Investigation by NHTSA for Front Suspension Failure

Tesla Auto Maker owned by eccentric billionaire Elon Musk is under investigation by the United States National Highway Traffic and Safety Administration know otherwise as the NHTSA. They are looking into 115 thousand some Tesla vehicles that have front suspension safety issues.

The United States National Highway and Traffic Safety Administration said it was opening a preliminary evaluation into the 115, 000 Model S vehicles from 2015-2017 and Model X vehicles from 2016-2017. This comes after they received 43 complaints that claimed there was a failure in the right or left front suspension fore forks.

Tesla made an announcement about the possible issue in a service bulletin that discussed a manufacturing condition that they said could result in a front suspension link failures, the National Highway Traffic and Safety Administration said.

 

Audi Developing Energy Generating Suspension

Think of all the things that cause loss of energy in a vehicle: mechanical friction, braking, aerodynamic drag, etc. As Audi enters the electric and hybrid market with the release of their first-ever plug-in hybrid, the A3 e-tron and their development of their so-called all-electric super car, the R8 e-tron, Audi seem almost obsessive on their “search and destroy” mission when it comes to energy drains. With this set of lenses Audi has turned it’s eyes to suspension.

Strangely enough, yes, suspension—Dr. Ulrich Hackenberg, Audi R&D chief, discussed the companies work on their “generator suspension that will hopefully make it into future productions.”

“What people don’t realize is that dampers get very hot,” he said. “When working hard over a bumpy road, the dampers are perhaps 100 to 125 degrees. This energy is wasted as heat into the atmosphere. So, we will replace the suspension with a generator.”

Audi is looking into the possibility of using a rotating generator inside each damper that could be spun during compression and rebound. Then, captured electrical energy could be directed to batteries for storage. This energy could provide power for an electric or hybrid’s drive system or electrical accessories. Bumps in the road could power your radio! Dr. Hackenberg even offered some ideas on how such a energy recycling suspension system to could benefit performance cars:

“Because we can send energy back into the damper, you will have an independently variable suspension. This can [mitigate body] roll.”

Joe asks Jody Victor®:12 Cars We Can’t Wait to Drive

The annual North American International Auto Show in Detroit can induce serious sensory overload. For a true car nut, it’s like being a kid in a candy store – drooling over all that tasty sheet metal. I asked Jody Victor  to tell us about 12 of them (in 3 instalments) from an article by Kirk Bell of MSN Autos, and msn.com.

Jody Victor: Hey Joe, can’t wait to see and drive some of these fantastic vehicles. Here’s the first batch.

Acura NSX Concept – The original NSX was the everyman’s supercar. The car, sold in the U.S. from 1990 to 2005, wasn’t overly powerful, but handled like it was on rails thanks to a low curb weight, ideal weight balance and a low center of gravity. The all-new NSX, which is due out within the next three years, will rely on technology to achieve the same — or, hopefully, better — results in the twisties. The concept’s midmounted V6 engine is connected to a dual-clutch automatic transmission with a built-in electric motor that sends power to the rear wheels. An additional pair of electric motors sits at the front axle to provide all-wheel drive. This new setup can shuttle torque from left to right just like in Acuras equipped with current SH-AWD, although in the NSX it’s done electrically.

2013 Audi S4 – The Audi S4 doesn’t get an appreciably new look for the 2013 model year, but it does retain the traits that have made it one of our favorite sport sedans. It’s still well-balanced, and handling is still aided by lightweight aluminum suspension components and the Audi drive select system, which includes adjustable shock absorbers. The 333-horsepower 3.0-liter supercharged V6 engine offers plenty of willing power and decent fuel economy. Our only concern is the new electric-assist steering. Let’s hope it has as much road feel as, or more than, the outgoing hydraulic system.

2013 Cadillac ATS – When an automaker is serious about developing a car with world-class handling, it sends a group of engineers to test that vehicle on Germany’s famed Nurburgring road circuit. Cadillac did just that with the 2013 ATS compact sedan. Designed to compete with the BMW 3-Series, the ATS has true sport sedan credentials: low mass (it will be the lightest car in the class), extensive use of high-strength steel, rear- or all-wheel drive, Magnetic Ride Control suspension and Brembo brakes. We are looking forward to both the turbocharged 2.0-liter 270-horsepower four-cylinder and the 3.6-liter 318-horsepower V6 engines.

2013 Chevrolet Sonic RS – The Chevrolet Sonic was one of the pleasant surprises of 2011. Its solid structure gives the car a dynamic character unmatched in its segment. The 1.4-liter turbocharged engine, while a bit underpowered in the Chevy Cruze, is right at home in the lighter Sonic. The RS is a sportier version of the likable subcompact. With a lower stance and stiffer suspension, the RS will be even more agile than the base car. Revised gearing should make it slightly quicker, and some exterior modifications make it look a little meaner. We’ll go so far as to say the Sonic RS could be the poor man’s GTI.

Thanks, Jody! More next time!
