Aerodynamics

It's not uncommon for cyclists to carry snacks, phones, wallets or other items in a handlebar-mounted bag when out for a ride. Unfortunately, though, putting a block-shaped bag right on the front of the bike doesn't do wonders for its aerodynamics. That's why Slovenian inventor Joze Petkovsek created the Speed Up Bag. Not only is it sleeker than a regular bag, but a bicycle equipped with one is claimed to produce less wind drag than one with no bag at all. Read More
If there's one thing that needs to be aerodynamic, it's an airplane wing. Conventional wing designs however, suffer from a glaring weakness in this respect: the joint where the main wing meets the trailing flaps. Michigan-based FlexSys has developed a way to optimize wing aerodynamics with FlexFoil, a seamless variable geometry airfoil system that could deliver fuel savings of up to 12 percent. Read More
Professor J.C. Chiao and his postdoc Dr. Smitha Rao of the University of Texas at Arlington have developed a MEMS-based nickel alloy windmill so small that 10 could be mounted on a single grain of rice. Aimed at very-small-scale energy harvesting applications, these windmills could recharge batteries for smartphones, and directly power ultra-low-power electronic devices. Read More
The holidays are a time for stocking stuffers and BMW has given us one with a hint of what’s to come in the new year. On Monday, the car maker announced that it would present the new Mini John Cooper Works concept at the North American International Auto Show (NAIAS) 2014, running January 13 to 26 in Detroit. Since we’re getting just a taste of what is still a concept, there aren’t a lot of details and BMW is keen to talk more about style than engineering, but we do get a bit of an idea of what this track-oriented concept is about.

The Boz is not a car, and you won't be able to buy it. According to new start-up Zoox, the Boz is the transportation paradigm that comes after the car. It's but a fanciful idea from an unknown start-up for now, but the company believes it can finish its thought by 2021. Read More
Urbee 2, the first road-ready, fuel-efficient car built using 3D printing, is the subject of a collaboration between design firm KOR EcoLogic, direct digital manufacturers RedEye On Demand, and 3D-printing manufacturer Stratsys. Their aim is to put the 7 hp (5 kW) three-wheeled, rear-steering eco-hybrid on the roads by 2015, and then demonstrate its capabilities by crossing the US using only ten gallons (38 L) of fuel.

The setting is a private house located two miles off a Californian highway, up a very narrow, misty road. There waiting in the driveway is Lamborghini’s $4 million rolling concept, the Veneno. Next to it is the rolling reality of an Aventador LP 700-4, and it's time for a test drive. Read More
Italian supercar maker Lamborghini is celebrating its 50th anniversary in 2013 and Gizmag recently had the pleasure of sitting down with Lamborghini's CEO Stephan Winkelmann and Design Director Filippo Perini for a fascinating insight into one of the automotive world's most exotic brands. Read More
Now that the media kerfuffle surrounding Elon Musk's Hyperloop transit system proposal has settled down to a dull roar, it's a good time to step back and consider in detail some of the real innovations and difficult issues raised through analysis of the 57-page Hyperloop plan. Read More
The world record price for a car at auction was smashed this month when Juan Manuel Fangio's 1954 Mercedes W196 F1 Silver Arrow sold for US$30 million, doubling the previous auction record. The only W196 outside of Daimler Benz or an internationally-recognized museum, this car won its first two starts – the 1954 German GP at Nürburgring and the Swiss GP at the uber-frightening, tree-lined Bremgarten circuit – and sealed the 1954 World Drivers Title for Juan Manuel Fangio, statistically the best racing driver in history. The following year, it was released in roadgoing form to become the world's fastest road car: the legendary Mercedes 300 SLR (aka W196S). Read More
