Drivers buy new $300K McLaren 720S, 2019 Chevy Corvette, and wreck 'em

Two high-powered, high-priced sports cars, wrecked in their infancies. No doubt they were fun while they lasted. In Great Falls, Va., a tony suburb of Washington, D.C., that hugs the Potomac River, someone was out enjoying driving the McLaren 720S they had purchased only the day before on a leafy, two-lane road. Then, horror: In an instant, the car hit a tree, mangled and destroyed "because of speed," according to the Fairfax County Police Department. Purchased Friday. Totaled Saturday. This McLaren 720S, costing around $300,000, was destroyed today in Great Falls because of speed. The driver was taken to the hospital with thankfully only non-life threatening injuries. A reminder to slow down, or it could cost you. pic.twitter.com/XhC3LKRY1t — Fairfax County Police (@FairfaxCountyPD) July 14, 2018 Then on salvage auction site Copart, a brand-new orange 2019 Chevrolet Corvette Grand Sport lies in a warehouse in Lincoln, Neb., its front left corner crushed, wheel askew. It had just 15 miles on the odometer. We know nothing of the backstory, except for the obvious front-end damage and secondary damage to the undercarriage. The rear end and 6.2-liter V8 engine, which makes 460 horsepower and 465 pound-feet of torque, look OK. The most current bid as this was published was just north of $9,000. It's tempting in both cases to assign the blame to over-eager drivers who weren't quite yet able to corral all that power. In the case of the McLaren, the supercar makes 710 horsepower and 568 pound-feet of torque from its quad-cam, twin-turbo 4.0-liter V8. It goes from 0-62 miles per hour in 2.9 seconds and boasts a top speed of 212 mph. We're not saying the unidentified driver was a newbie, but this car is definitely not for newbies. Police write that the incident is "A reminder to slow down, or it could cost you." As in, $300,000. Or at least the depreciation for driving it off the lot. Related Video:

Recharge Wrap-up: NEDC's NOx problems, autonomous Chevy Volts

The International Council on Clean Transportation (ICCT) found a significant difference in NOx emissions in Euro 6 diesel cars in NEDC and WLTC testing. While 88 percent of the cars tested met emissions standards for NEDC, NOx emissions averaged five times higher under WLTC, with only 27 percent of vehicles under the limit. WLTC is considered to be a more realistic driving cycle, using hot starts and factoring a higher top speed as well as harder and more frequent accelerations than the NEDC.

Employees will be able to use a carsharing app to reserve a car, which will then drive itself to the set destination. The project will allow GM to collect important data and experience to help the company more quickly develop autonomous driving technology.

The lithium-ion batteries used to power the EV were recycled from other Renault EVs. With the electric Trafic, Carwatt – a company that converts vehicles to use electric power – aims to demonstrate the "circular economy" of batteries, which can provide more value through a longer lifecycle. Read more in the press release below. Carwatt presents a unique automotive application for second-life batteries from electric vehicles. On the sidelines of the COP21 summit, in the Solutions Gallery running from 2 to 9 December 2015 in Le Bourget near Paris, Carwatt and its partners —Renault, Paris City Council, BPI France, the Ales Ecole des Mines Engineering School, and the Bobigny Business Campus — are showing a very special electric Renault Trafic. This prototype vehicle, the only one of kind in the world, is powered by second-life lithium-ion batteries recycled from Renault electric cars. Circular economy at work with electric vehicles When, over time, the batteries of a Renault electric vehicle fall the performance threshold specified for their initial automotive power duty (around 75% of initial capacity), they can still provide valuable service in "second-life" applications before end-of-life disposal at a recycling centre. Experiments are already under way on power storage applications, for example.

NHTSA approves hybrid rearview mirror display in Cadillac CT6, Bolt EV

The Chevy Bolt EV prototype doesn't just have a fancy new all-electric powertrain. Just outside the driver's line of sight is a newfangled rearview mirror, one that can turn into a screen that shows a moving image from the rear-facing camera. Speaking to NPR's Robert Siegel yesterday, Department of Transportation secretary Anthony Foxx said that NHTSA has now approved this type of mirror/screen for use in vehicles. According to a letter from NHTSA to General Motors, GM will likely use this Full Display Mirror first in the 2016 Cadillac CT6 before coming to the Bolt. In its letter to GM, NHTSA said that the Full Display Mirror will only qualify as a standard rearview mirror as long as there are normal side mirrors in place. In other words, don't expect to see cameras and screens replacing all the mirrors in a motor vehicle just yet. @AutoblogGreen @NPR - #NHTSA has OK'd GM rear-view system that can switch between mirror & camera views. pic.twitter.com/6CBeIit10v — Anthony Foxx (@SecretaryFoxx) February 22, 2016 The Full Display Mirror was developed by Gentex, which has long worked with GM. The FDM debuted in 2014 and some people hoped it would also make its way into the Tesla Model X. Gentex, which also makes auto-dimming mirrors, says that it has "set out to develop the technologies and core competencies necessary to manage this evolution of the rearview mirror." The Chevy Bolt EV will start at $37,500, before incentives. The 200-mile EV will go into production late this year for likely sale in early 2017. Related Video:
