2010 Opel Flextreme GT/E Concept with E-REV Drive System

Think of the Opel Flextreme GT/E concept as a bigger Chevrolet Volt (or Opel Ampera if you're European). The idea behind this concept, which will debut at the Geneva Motor Show (March 4 - 14, 2010), is to show how the Volt's extended-range electric vehicle drivetrain can be used in a larger vehicle, in this case a mid-size five-door hatchback. And it will boost the company's credentials as a leader in green technologies, offering expressive design with efficient environmental performance - and engineered with German precision.

In Opel's strategy for achieving more independence from fossil fuels, electricity plays a key role. The 4.7-meter long Opel Flextreme GT/E Concept illustrates how extended-range electric vehicle (E-REV) technology can be plugged into large or mid-size vehicles, as well as compact cars such as the upcoming Opel Ampera. Opel calls this strategy e-mobility unlimited: adapting the highly efficient E-REV drive system - which removes the limitations of battery-only power - to vehicles across all market segments. To enjoy zero CO2 driving emissions Opel-style, the Flextreme GT/E concept shows that size doesn't matter.

The purposeful design also enables the Opel Flextreme GT/E Concept to achieve a projected drag co-efficient of just 0.22, which helps it reach a 200 km/h-plus top speed as well as conserve energy and extend its driving range. Stand-out visual features include a low and wide stance, wing-shaped lights front and rear, a distinctive nose and grille, floating C-pillars and muscular, sculptured bodywork.

The clean, frontal styling features a low hood line and an extended nose section, which is clasped by wing-shaped, signature LED headlamps. These are deeply carved into the front fenders and across the hood line. The new trapezoidal grille execution is slim but bold. The prominent wing-shaped chrome bar carries a large Opel emblem, which doubles as a socket for charging the Opel Flextreme GT/E Concept's battery pack. The upper section of the grille is used to admit cooling air, the lower portion being covered by a translucent panel. The absence of additional air intakes allows a low frontal area for aerodynamic efficiency and also enables the Opel Flextreme GT/E Concept to meet future pedestrian protection requirements.

In profile, the Opel Flextreme GT/E Concept is distinguished by innovative, stubbed C-pillars. This floating design allows the glasshouse to be extended rearwards under the arching roofline, emphasizing the flowing lines of the side body. The car's dynamic character is further underlined by a fresh expression of Opel's signature blade motif, now a swooping swage line from the base of the C-pillar into the lower front fender. The translucency of the fixed glass panel in the center of the roof is adaptive, allowing sunlight to warm the interior in the cold of winter, but darkening for coolness in summer. A duct at the rear edge of the roof is for additional cooling of the battery and electronic components.

Integral to the Opel Flextreme GT/E Concept's expressive looks is the efficiency of the design execution. The small frontal area, low roof height (1308 mm) and a flat, enclosed underbody all enable the car to cleave the air with a minimum of disturbance. The 21-inch alloy wheels are relatively narrow, to reduce wind resistance, and fitted with 195/45, low rolling resistance tires. Clear, flush-mounted trim inserts also minimize air turbulence.

The Opel Flextreme GT/E Concept also explores the potential for active shape shifting. At speeds above 50 km/h, a vertical panel extends along the body from the air extraction slot behind each rear wheel-arch. These 350 mm-long side spoilers guide high-speed airflow around the rear corners of the car, further reducing the amount of turbulence.

Mass reduction measures for the body include the use of lightweight, carbon composite outer panels, polycarbonate window glazing and aluminum alloy structural components. Compared to conventional materials, these offer a 40 percent weight saving which further contributes to reduced energy consumption and an increased driving range.

The efficient concept also includes GM's ground-breaking E-REV drive system, already developed for the Opel Ampera. The Opel Flextreme GT/E Concept shows the versatility of this technology by displaying it in a larger, mid-size vehicle format.

2010 Opel Flextreme GT/E Concept with E-REV Drive System

Despite its greater size and a maximum speed of more than 200 kilometers per hour, the Opel Flextreme GT/E Concept is projected to offer performance similar to that of the Ampera: a battery-powered driving range of up to 60 km - with zero CO2 tailpipe emissions - and a total range of more than 500 km. Average fuel consumption is estimated at 1.6 l/100 km, with CO2 emissions of less than 40 g/km. Unlike a hybrid vehicle, the wheels of the Opel Flextreme GT/E Concept are powered at all times by electricity. For typical journeys up to 60 km, energy is supplied by a T-shaped lithium-ion battery pack located under the floor and rear seat.

However, unlike a battery-only electric vehicle, the Opel Flextreme GT/E Concept eliminates any possibility of range anxiety through fear of being stranded without power. The small gasoline engine/generator is seamlessly engaged to provide electricity whenever the battery's supply becomes depleted. In this mode, the driving range is extended to more than 500 km, until the plug-in battery pack can be recharged or the car is refueled. The motor in the electric drive unit delivers a substantial 370 Nm of instant torque, giving lively performance and projected zero to 100 km/h acceleration in less than nine seconds.

The Flextreme GT/E concept is a further step in Opel's unfolding strategy for the electrification of the automobile, which includes a wide portfolio of products using battery, extended-range, hybrid and fuel cell technologies.

Bentley AERO ACE Sports Car Concept Next-Gen Speed VI

The Bentley Aero Ace Speed VI is the brainchild of auto designer Gabriel Tam and has been inspired by the original Speed 6 driven to victory by the Bentley Boys of the ’20s at Le Mans. The next-generation Speed VI is an overtly sporting vehicle with the raw aggression of a pure blood racer, while retaining the refined elegance of past Bentleys.

Chevrolet CORVETTE Racing at Sebring 2010

Back in August when General Motors introduced the all-new GT2 class Corvette C6.R, it ran downsized 6.0-liter version of the 7.0-liter V8 from the long-dominant GT1 car. At the launch, Corvette Racing program manager Doug Fehan told us the 6.0-liter was just an interim engine. With revised GT rules on tap for 2010, GM was already planning a brand-new engine for its race Vette.

Unlike the 6.0/7.0, which is a ground-up race engine that only shares basic architectural dimensions with the production small block, the 2010 C6.R's V8 is a new 5.5-liter unit that will indeed be derived from the production engine found in roadgoing Corvettes. In fact, the 5.5-liter race engine will be built at GM's Performance Build Center alongside ZR1 and Z06 V8s.

Fehan has confirmed that the 5.5 is running on the dyno and will make its race debut at the 12 Hours of Sebring in March. We don't have any additional details on the new engine yet, although we were told earlier that it is based on the next-generation production small-block, which we expect to see in the Corvette soon

Chevrolet CORVETTE Racing at Sebring 2010

Corvette Racing is preparing for the season-opening round of the 2010 American Le Mans Series, the Mobil 1 Twelve Hours of Sebring, to be held in Sebring, Fla., on March 20. Forty years ago, Sebring set the stage for some highly competitive racing among Cobras, Ferraris, and Corvettes.

Difficult weather and trying mechanical situations added a challenging dimension to an exciting event. In light of recent C5-R successes and the impending start of yet another season of American Le Mans Series competition, a look back at the effort put forth by the privateer Corvette camp lends amazing perspective.

Chevrolet CORVETTE Racing at Sebring 2010

Corvette Racing will compete in the GT (formerly GT2) class against entries representing Porsche, Ferrari, BMW, Jaguar, and Ford. Corvette Racing drivers Johnny O'Connell, Jan Magnussen, and Antonio Garcia are testing the No. 3 Compuware Corvette C6.R. Oliver Gavin, Olivier Beretta, and Emmanuel Collard are testing the No. 4 Compuware Corvette C6.R.

2010 Super Hatchback Concept Car by Jamie Martin

Details on a possible future eco-friendly model, called SHC (Super Hatchback Concept), were revealed by designer Jamie Martin, a UK based designer whose previous works include the Cobra Venom V8 concept and the London Navigator bus. The SHC was conceived out of a desire to fuse the two very different worlds of hatchbacks and supercars. And in a world where limiting CO2 output is becoming increasingly important, the SHC also has some green tech up its sleeve.

Designed to compete against the likes of the Honda Civic Type-R and Ford Focus RS, the SHC would be offered with a choice of two different engine/transmission packages.

It has similarities to both a supercar and a 3-door hatchback and boasts of both styling and performance characteristics. The concept car is available in a choice of three next generation powertrains, including an electric / hybrid option. Interestingly, the body is composed of 65% Steel and 35% aluminum used for front wings, bonnet & bumpers. Alternatively, 30% glass reinforced plastic can be used for designated sections.

Other features include front and rear window ‘air-streams’, combined with hydrophobic and super-fast screen heating and high-intensity LED/Single-Source fiber-optic illumination used on the headlight wing, lower fog light, and rear lights. Martin describes the car to have a “balanced formula of raw power, racing spirit, practicality and eco engine choices.” He said that this means that you have a supercar-inspired drive to use for weekly shopping.

The first proposed powertrain of the concept consists of a twin-turbocharged internal combustion engine with direct injection, stop-start technology and regenerative braking. Transmission would be via a 6-Speed Short-Shift manual gearbox or a 7-speed paddleshift auto.

The second option is a system dubbed the 'Delta Drive Hybrid (DDH)'. This setup consists of a smaller displacement internal combustion engine and a pair of electric motors. Nano-Titanate batteries located in the engine bay, and under the floor would feed power to the high-torque electric motors mounted within the front wheels. 3-performance modes would be available: Economy (low bhp town driving), Normal (medium bhp - motorway driving), and Performance (high bhp - utilising both the petrol engine and electric generator together for ultimate power). The car could also be driven in full electric mode for around 70 miles before the engine was needed to recharge the batteries.

Further highlights of the SHC include a magnetorheological fluid suspension system with Normal, Sport & Track modes. This system, first used by Ferrari, features dampers with iron filings suspended in fluid. When an electrical current is passed through the fluid it instantaneously changes the damping rate and stiffens up the suspension.

While the SHC is just an independent concept with no intention of production, it does seem more and more likely that hybrid technology will filter very quickly into performance vehicles - and hot hatches could be one of the first segments to make the switch.
