Tesla Model S costs one nickel per drag race [w/video]

Historically, the intersection between electric vehicles and drag racing has been really small - or so we guess, at least. But the advent of Tesla in the auto marketplace, and the subsequent performance offered up to drivers by way of battery-powered cars, has caused even racy publications like DragTimes to get in on the action.
Having posted several YouTube videos featuring the Tesla Model S doing pulls at the local strip, DragTimes encountered questions about just how many races that car might be able to run before needing to re-juice its battery pack. The publication monitored the energy being used by the Tesla during full-throttle, quarter-mile runs, and determined that the net use (after energy from the regen braking was added back in) amounted to just 0.5 kWh per go. Considering that the full battery capacity is 85 kWh, DragTimes figured that the Model S is good for a remarkable 170 races before needing a recharge. By that math, and using electricity costs in DragTime's home state of Florida, each race would cost just a nickel and a penny's worth of electricity.
With respect, that theoretical number is probably way too high. For starters, the car would expend some energy getting to and from the starting line between races. Perhaps more critically, the system is designed to not allow for a completely full charge or deletion of charge, so the car can't use all 85 kWh. Still, 100 runs is in the realm of possibility. In the video below, the narrator makes mention of 150 runs, which is optimistic but more likely. Cheap thrills, in any case (once you've paid for the car).

Autoblog Minute: Ferrari F12 TdF, Tesla Autopilot, Fiat brand leadership change

Ferrari unleashes the F12 TdF, Model S owners get an exciting announcement from Tesla, and Fiat North America undergoes a leadership change. Senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Ferrari unleashes the F12 TdF, Model S owners get an exciting announcement from Tesla, and Fiat North America undergoes a leadership change. I'm Senior editor Greg Migliore, this is your Autoblog Minute Weekly Recap. Ferrari's new F12 TdF gets its name from the legendary Tour de France race that Ferrari dominated back in the 50s and 60s. [00:00:30] This new Ferrari is derived from the naturally aspirated F12 Berlinetta's engine. There are styling and performance upgrades, and the company highlights changes in aerodynamics, weight reduction, and faster shifts. The result, Ferrari says, is a blistering zero to sixty-two time of, 2.9 seconds. It's pretty fast. Tesla released software version 7.0 for Model S owners. The big takeaway from this update is the much anticipated Autopilot mode. Tesla says Autopilot [00:01:00] allows Model S to steer within a lane, change lanes, and manage speed. Software version 7.0 will also allow for digital control of the motors, brakes, and steering for collision prevention. Now do you hate parallel parking? Tesla's got you covered. The Model S can park on command, right after it scans for a spot and alerts you when one becomes available. Jason Stoicevich resigns shortly after losing control of the Fiat brand. Automotive News reported that Stoicevich's leadership role at Fiat was handed over to the company's [00:01:30] head of the Dodge brand. That's Tim Kuniskis. The report cites diminished sales figures as a key reason for the personnel change at Fiat. This change resulted in Stoicevich leaving FCA altogether. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday. Plus I'll have some added insight into BMW's M2. For Autoblog, I'm Greg Migliore.

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.
