Investigators Find No Defect Trend With Tesla Motors' Model S

Federal safety investigators said Friday they have found no apparent defect trends in the Tesla Model S, an electric luxury car that has its share of fans and critics. The National Highway Traffic Safety Administration closed a four-month investigation into whether the car's batteries were at heightened risk for underbody strikes and subsequent fires. Even though no defect trend was found, Tesla Motors said in a written statement it would further protect the bottom of its cars with a reinforced underbody shield. The California-based automaker started adding the shields on March 6 and will retrofit older models free of charge. It will also increase the ground clearance of new cars. "This fix should eliminate the potential of a battery-pack fire under all but the most extreme circumstances," said Karl Brauer, a senior analyst at Kelley Blue Book. Although there are more than 194,000 car fires in the United States every year, NHTSA investigators began a preliminary investigation into potential trouble on Nov. 15, 2013 following two Model S fires, one in Tennessee and one in Washington. No one was injured or killed in either fire. Roadway debris punctured the battery pack near the front of the compartments in both cases, damaging the batteries' lithium ion cells that then began "thermal runaway" events. The opposite ends of the debris had dug into the pavement and jutted upward. Tesla called this a "piking effect." The company said it has conducted 152 vehicle level tests, and that the new shields prevented any damage or penetration of the new shields. The first is a rounded, hollow aluminum bar that's followed by a titanium plate. The third layer of protection is made of solid aluminum. (There's video of the new plates in action on the Tesla Motors website). "We have tried every worst-case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event," Tesla Motors founder Elon Musk wrote on the company's blog," essentially equivalent to driving a car at highway speed, into a steel spear braced on the tarmac." Approximately 15,805 vehicles are eligible for the upgrades, which NHTSA says should reduce the frequency of underbody strikes and subsequent fire risks. But the agency did note that the closing of the investigation did not necessarily constitute a finding that a defect does not exist. "The agency reserves the right to take further action if warranted by new circumstances," it said.

Fastest and most powerful SUVs in America for 2022

Here in the United States, we enjoy power almost as much as we like our SUVs. Thankfully, we’ve got plenty of both. Traditionally, the most powerful SUVs source their massive horsepower and torque from some form of a V8. While thatÂ’s still generally the case, electrification comes into play more and more, whether itÂ’s mild-hybrid tech, a plug-in hybrid powertrain or, as is the case with the two vehicles topping this list, fully electric vehicles. As we enter the 2022 model year, letÂ’s look at the most powerful SUVs available.  Before we dive in, letÂ’s address the elephant that is waiting just outside the door. Due to supply shortages, Mercedes-Benz is shelving most V8 models for the 2022 model year. Some 2021 models can still be found in dealer inventories, but we wonÂ’t include them. With that in mind, letÂ’s dive into the list. 2022 Audi RS Q8 — 591 hp / 190 mph Read our review of the Audi RS Q8 The only Audi on this list is a hot little number, which we characterized as “an uncompromising option in a field of compromised options.” Powered by a 4.0-liter twin-turbo V8 (which seems to be a popular format in this list), its 591 hp and 590 lb-ft of torque get it scootinÂ’ to 60 mph in just 3.7 seconds, and on to a top speed of 190 mph. It even has the bragging rights of holding the Nurburgring lap record for an SUV.   2022 Rolls-Royce Cullinan Black Badge — 592 hp / 155 mph (limited) Read our review of the Rolls-Royce Cullinan This is one SUV where being a passenger might be more exciting than sitting in the driverÂ’s seat, thanks to over-the-top luxury — what do you expect from a car that costs over $350,000? The driver doesnÂ’t go unrewarded, though, with a turbocharged 6.75-liter V12 at their disposal. Thanks to the Black BadgeÂ’s software upgrade, it makes 592 hp and 664 lb-ft of torque to help get to its electronically limited top speed of 155 mph that much quicker.    2022 BMW Alpina XB7 — 612 hp / 180 mph Read our review of the BMW Alpina XB7 Alpina takes already impressive BMW vehicles and turns them into even more powerful, more luxurious machines. The Alpina XB7 improves upon the BMW X7 with a biturbocharged 4.4-liter V8 offering up 612 hp and 590 lb-ft of torque. ThatÂ’s good for a 4.0-second 0-60 sprint and a 180-mph top speed. Alpina also adds its own transmission and drivetrain tuning, upgraded suspension, exhaust and a whole slew of unique appearance touches.

Recharge Wrap-up: Panasonic, Tesla on Gigafactory deal?

Bentley has been awarded the Carbon Trust Standard for reductions of carbon, water use and waste production in manufacturing. The Carbon Trust is an organization that helps groups such as businesses and governments reduce carbon emissions, use of energy and resources, and waste output. From 2011 to 2013, Bentley reduced CO2 emissions by 16 percent per car manufactured, curtailed water use by 35.7 percent, and saw significant waste reductions. Darran Messem of Carbon trust says, "Bentley is clearly passionate about continuing to improve its environmental performance, which is reflected by the fact the company has consistently invested in new technology."

The organization will use the range-extended electric cars in its efforts to help MBA students learn from and work with small business owners. As part of the MBAs Across America program's first year, four students drove 8,000 miles to provide entrepreneurs with free business counseling. The program has expanded, and this year, teams of MBAs will use the Volts to travel to 25 cities to offer their services. Learn more about the partnership between Chevrolet and MBAs Across America in the press release below. A professor from the University of Michigan has found fuel cycle analysis to be too flawed to be relied upon for measuring CO2 impacts of transportation fuels. Professor John DeCicco of the university's Energy Institute feels that the flaws in calculating the carbon footprint of liquid fuel production and combustion make such lifecycle analysis impractical. He suggests, instead, to focus to carbon capture. Since capturing CO2 directly from a vehicle is probably never going to happen, DiCicco believes the solution is to capture carbon from the atmosphere in sectors outside of transportation. Says DiCicco, "Research should be ramped up on options for increasing the rate at which CO2 is removed from the atmosphere and on programs to manage and utilize carbon fixed in the biosphere, which offers the best CO2 removal mechanism now at hand. Such strategies can complement measures that control the demand for liquid fuels by reducing travel activity, improving vehicle efficiency and shifting to non-carbon fuels."
