Θυμάσαι τη μπλε Corvette Stingray που είδαμε σε αυτό το video; Ε, αυτή πλέον καταγράφηκε ως η πρώτη τρακαρισμένη νέα Corvette σε δημόσιο δρόμο παρόλο που επίσημα ακόμα δε ξεκίνησε να πωλείται, μέχρι το καλοκαίρι.
Το ατύχημα έγινε στην Αριζόνα τις προηγούμενες μέρες και σύμφωνα με ένα μέλος του forum Digital Corvettes, το συμβάν έγινε σε ένα γεμάτο στροφές βουνίσιο δρόμο της Αριζόνας και το αμάξι είναι σε χειρότερη κατάσταση απ’ότι φαίνεται στη φωτογραφία καθώς προηγούμενα είχε χτυπήσει τη προστατευτική μπαριέρα και μετά έπεσε στους βράχους.
Κρίμα αλλά πιστεύω ότι έχουμε να δούμε και άλλες στο μέλλον!
Bonus! Δες και ένα νέο διαφημιστικό spot που έβγαλε η Chevrolet για τη νέα Vette καθώς και ένα ακόμη video στο οποίο μας περιγράφει την ελαφριά κατασκευή της.

DETROIT – From its fiberglass body in 1953 to its aluminum chassis for 2014, Chevrolet Corvette has a six-decade track record for introducing lightweight materials that improve vehicle performance. With the 2014 Corvette weighing in 99 pounds lighter than its predecessor, that trend continues.
The redesigned seventh-generation sports car is the first vehicle to use a General Motors’-developed lightweight shape memory alloy wire in place of a heavier motorized actuator to open and close the hatch vent that releases air from the trunk. This allows the trunk lid to close more easily than on the previous models where trapped air could make the lid harder to close.
Considering there are about 200 motorized movable parts on the typical vehicle that could be replaced with lightweight smart materials, GM is looking at significant mass reduction going forward.
Shape memory alloys – typically made of copper-aluminum-nickel or nickel-titanium – are smart materials that can change their shape, strength, and/or stiffness when activated by heat, stress, a magnetic field or electrical voltage. Shape memory alloys “remember” their original shape and return to it when de-activated.
In the new Corvette, a shape memory alloy wire opens the hatch vent whenever the deck lid is opened, using heat from an electrical current in a similar manner to the trunk lights. When activated, the wire contracts and moves a lever arm to open the vent, allowing the trunk lid to close. Once the trunk lid is closed, the electrical current switches off, allowing the wire to cool and return to its normal shape, which closes the vent to maintain cabin temperature.
“Smart materials like shape memory alloys offer new possibilities for many movable vehicle features,” said Jon Lauckner, GM’s chief technology officer. “These new materials enable innovative designs and new and improved features at a lower cost than traditional motors and actuators.”
Shape memory alloy also helps remove unwanted mass, which can help improve vehicle performance and fuel economy. The wire actuator used on the new Corvette is approximately 1.1 pound (.5 kilogram) lighter than a conventional motorized system.
“The shape memory alloy used on the new Corvette represents nearly five years of research and development work on smart materials for which GM has earned 247 patents,” said Paul Alexander, GM smart materials and structures researcher. “And it is just the beginning. We have many more smart material applications in the pipeline that will bring even more improvements to our vehicles going forward.”
Founded in 1911 in Detroit, Chevrolet is now one of the world’s largest car brands, doing business in more than 140 countries and selling more than 4.5 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.
