Mercedes Concept IAA shape-shifts for improved aerodynamics

As emissions standards get tougher, manufacturers are being forced to think outside the box in the quest for better fuel economy. One of the obvious areas to focus on is aerodynamics, where small tweaks can lead to big fuel savings. Shape-shifting designs represent one of the more radical approaches in this area, and Mercedes has taken this to another level with its Concept IAA (Intelligent Aerodynamic Automobile), which changes shape at higher speeds to cut through the air more efficiently.

Freightliner SuperTruck shows other transport trucks how efficiency is done

Back in 2009, the US Department of Energy issued its SuperTruck Challenge. The program provided funding for truck manufacturers to design and build a prototype vehicle that was at least 50 percent more freight-efficient than a baseline 2009 truck. Daimler Trucks North America recently unveiled its response – the Freightliner SuperTruck. It goes beyond the 50 percent figure, with a claimed efficiency increase of 115 percent. Read More

Pininfarina's aerodynamic 1960 X Concept was 50 years ahead of its time

The name Pininfarina is synonymous with expensive and elegant Italian sports cars such as the Maserati GranTurismo, Alfa Romeo Spyder and a log file of Ferraris such as the 365 GTB/4, Enzo, F40 and Testarossa. The global design legend does much more than style beautiful cars though, and ample testimony will appear at auction this week in the form of a little known 1960s concept car. With its four wheels arranged in a diamond shape, the tiny aerodynamic four-seater Pininfarina-X had a drag coefficient of 0.23, indicating that Pininfarina was a long way ahead of the rest of the world in exploring the critical area of aerodynamics, long before it was fashionable.

New 1035 hp Ferrari FXX K hybrid based on LaFerrari

Ferrari's new 1035-hp, 900-Nm FXX K (for KERS) hybrid is based on the 950-hp limited-edition LaFerrari hybrid supercar though it will never be sold or raced in sanctioned competition. Completely unfettered by homologation and racing regulations, the FXX K is part of a new research and development programme similar to the 599XX and FXX programmes which essentially involve laboratory cars designed specifically for the track and reserved for a select group of exclusive Ferrari client test drivers.

Beyond the car: Ultra-fast, ultra-efficient motoring with the Acabion Da Vinci

Peter Acabion, of Acabion GTBO fame, has released details of his next concept vehicle – an ultra-efficient, 1,200 mpg, 650 km/h, solar electric successor to the car. With four enclosed wheels, a transforming aerodynamic tail, a jet fighter style cockpit and a self-loading trunk capable of storing a whole washing machine, the four- to six-seater Acabion Da Vinci would use extreme aerodynamic profiling to squeeze vastly more speed and efficiency out of its available energy than any car currently available.

Airbus extends widebody aircraft family with A330neo

Airbus has announced the launch of the A330-800neo and the A330-900neo, which are the latest variants of the A330 two-engined widebody airliner that entered service in 1994. Airbus says that the A300neo aircraft use the new Rolls-Royce Trent 7000 engine and are the most cost-efficient wide-body aircraft on the market with 14 percent better fuel consumption per passenger seat compared to today's A330.
