China unveils world's fastest elevator


The Shanghai Tower may be the world's second tallest building.
But when it comes to speed, it's second to none.
    The 2,074 feet-tall skyscraper has installed a ground-breaking Mitsubishi elevator that travels at an incredible 20.5 meters per second (67 ft/s) -- faster than Usain Bolt can run (40 ft/s), but slightly slower than a cheetah (95 ft/s).
    No elevator in the world is faster.
    Visitors are whisked up to the building's viewing tower by the lightning fast elevator, from where they have unrivaled views of the Bund.
    The Shanghai Tower is not alone in its need for speed.
    In the Southern Chinese city of Guangzhou, home to 8.25 million, Hitachi this summer unveiled its fastest elevator in Guangzhou's tallest tower, the CTF, which stands at 1,739 feet tall.
    Its lift zooms from floors zero to 95 in an incredible 45 seconds -- or 20 meters per second (65 ft/s).
    It's not only China that is faced with the challenge of getting people through ever-taller towers with increasing efficiency.
    Reach 1km into the sky, the Jeddah Tower in Saudi Arabia will be the world's tallest building when completed in 2019.
    A building so tall, naturally, requires an exceptionally fast elevator.

    New Mercedes-AMG GT Roadster & GT C Roadster Officially Revealed [w/Video]

    Image
    Mercedes finally pulled the wraps off the  AMG GT’s Roadster version  which will come in two flavors: the basic 469hp model and the range-topping 547hp GT C model. The rumors were true then, as the new AMG GT C Roadster not only offers 46hp more than the AMG GT S Coupe but also borrows some of the technology found  in the manic AMG GT R .  More specifically, the new AMG GT C comes with the GT R’s rear axle steering, electronic locking differential and a wider rear track. Torque is rated at a peak 501lb-ft (680Nm), available from just 1900rpm. Mercedes reckons it needs 3.7 seconds to hit 62mph from a standstill, with the top speed electronically limited to 196mph (316km/h). The AMG GT Roadster on the other hand requires 4 seconds flat for the 0-62 procedure and won’t stop accelerating before hitting 187mph. Both models are powered by the same twin-turbo 4.0-litre V8 engine that has become the spine of AMG’s range, powering almost everything wearing their badge. As in the Coupe, a sev

    Volkswagen T-Roc Cabriolet Is A Crossover For Droptop Lovers

    Image
    Droptop crossovers have always been rather odd and the T-Roc Cabriolet is no different. It will be the only convertible Volkswagen on sale for the foreseeable future and will celebrate its public debut at the Frankfurt Motor Show in September. Rather than simply removing the roof of the standard T-Roc, Volkswagen has drastically altered the vehicle’s structure and body. In fact, its wheelbase is 37 mm longer than the standard T-Roc while its overall length is up by 34 mm. In addition, the Volkswagen T-Roc Cabriolet features structural strengthening in the underbody, side panels, cross members, doors, and windscreen frame to make up for the lack of a roof. The folding fabric roof developed by Volkswagen retracts in just nine seconds at speeds of up to 19 mph (30.5 km/h) and is similar in operation to the roof of the outgoing Golf Cabriolet. The presence of the soft top reduces trunk space by 161 liters down from the 284 liters of the run-of-the-mill T-Roc. We don’t think bu

    Limited Edition Ford GT 'Competition Series' Is All About The Track

    Image
    Ford's new GT Competition Series was built with weight-saving in mind, but also with an improved center of gravity for better road-holding. Among its features, you'll notice the lightweight carbon fiber racing stripes, A-Pillars and side mirrors, as well as the unique race-inspired Perspex acrylic engine hatch with integrated venting. Thanks to the manual latch and the carbon fiber prop rod, weight near the roof has been reduced, though Ford engineers went even further in their quest to make the car lighter, by making the bulkhead Gorilla Glass behind the driver about half as thick (and as light) as on other models. "The Ford GT has racing in its blood," said Ford exec Raj Nair, while adding that the Competition Series "was developed with the most hardcore track enthusiasts in mind, providing a tailored set of lightweight features and unique livery to match." There are also plenty of remaining performance features from the production car, such as
