E-tron Audi Spyder Concept 2010 a convertible sports car

Audi introduced the Audi Spyder Concept e-tron, the study of a roadster in the fall of 2010. The show car, with plug-in hybrid drive is 4.06 meters (13.32 feet) long, 1.81 meters (5.94 feet) wide and only 1.11 meters (3.64 feet) high. The two-seater is powered by a 221-kW (300 hp) twin-turbo V6 TDI in the rear and two electric motors that produce a total of 64 kW at the front.

Low total weight the Audi Spyder Concept-tron and weighs only about of 1,450 kilos (3,196.70 pounds) combined with high-torque TDI engine and two electric motors results in respectable yield. The car accelerates to 100 km / h (62.14 mph) in just 4.4 seconds and top speed is electronically limited to 250 km / h (155.34 mph).

The e-tron Audi Spyder Concept can combine the torque of his powerful TDI – diesel engine generates 650 Nm (479.42 pounds-feet) and the total of 352 Nm (259.62 pounds-feet ) of its two electric motors during acceleration in a process known as “momentum.”

Intelligent power distribution allows the optimal dynamic in each situation. The selective application of power to the front wheels improves the longitudinal dynamics while improving the dynamic lateral cornering. This is because torque vector – the required distribution of torque between left and right wheels of the two axes – permits a degree of precision driving exciting and excellent agility.

Thanks also to their low weight, short wheelbase and a perfect 50:50 weight distribution for dynamic handling, the Audi Spyder Concept e-tron has all the capability of driving a kart – good cornering and neutral law management to the limit too high.

The combination of a TDI unit and high-efficiency electric drive also provides excellent fuel economy and surprisingly low emissions. The e-tron Spyder Audi concept requires, on average only 2.2 liters diesel/100 km (106.92 miles per U.S. gallon), corresponding to CO2 emissions of 59 g / km (94.95 g / km) . A range of 1,000 km is possible with the tank of 50 liters (13.21 gallons U.S.).

The open sports car can also drive strictly on electric power and thus with zero emissions at distances of 50 kilometers (31.7 miles), and in urban areas. The maximum speed of 60 km / h (37.28 mph) is fine for normal driving.

Design:

The e-tron Audi Spyder Concept has what is undoubtedly the most advanced and also more consistent in the evolution of the current Audi design language, while also providing initial advice on the design language of future sports cars Audi.

To reinterpret the key design elements that characterize and previous e-tron vehicle concept. This also ensures the necessary formal differentiation to purely electric powered Audi e-tron is shown in Detroit 2010.

 

Their measures 1.81 meters (5.94 feet) wide, just 4.06 meters (13.32 feet) long and only 1.11 meters (3.64 feet) high: these are the classic proportions of an open car , high performance sports. Compared to the coupe concept car in Detroit, the length and width has increased by 13 centimeters (5.12 inches) and 3 cm (1.18 inches), respectively, to highlight the sporting aspirations of the design.

This further improved the overall appearance of powerful and compact features both vehicles and links to more sporty Audi production, the R8.

Due in part to the short wheelbase of just 2.43 meters (7.97 feet) – 22 cm (8.66 inches) shorter than the R8 – the body of the e-tron Audi Spyder concept becomes extremely robust.

In an obvious tribute to motorsport, frameless side windows taper surfaces downward to the rear. They are one with the windshield, which is heavily tilted and bent like the visor of a helmet.

Another element borrowed from race cars to the hood features: the entrance to the range of central air, which further accentuates the curve dynamics of the front of the vehicle and provides a visual and functional link to the Audi R8 race LMS client.

The front of the silhouette of the Audi Spyder and Concept-tron line is characterized by a clear, comprehensive two-seater that immediately identifies as an Audi. The sharply tapered front and lends the Audi Spyder Concept-tron clearly a basic form as a curve.

The trapezoid of the single-frame grill dominates the front clearly wedge-shaped and flanked by two large air intakes. They serve as cooling outlets for electric drive system and also for the TDI engine in the rear of the vehicle.

Above, the grid is based on flat strips of modules for adjusting the headlight beam matrix with clear glass in three dimensions that covers follow the contour of the functional elements.

All units of light using LED technology for ultra-efficient light. As with the R8 and e-tron sports car concept car, make four rings are above that of a single frame. Below the mark is the charging of the batteries.

The rings disappear under the front hatch, revealing not only the charging plug, but a screen that displays the charging status and a graphical map indicating the range of electric current.

Another distinctive feature of the show car wheels are 20 inches, bearing the design of the blades of the first car showroom e-tron and perfect in a turbine design in three dimensions. The wheels combine lightweight materials of aluminum and carbon in a design that is pleasing to the eye and very efficient aerodynamically. The 66 individual components comprising each wheel of the Audi Spyder Concept e-tron are indicative of how complex they are.

The line marks the shoulders of the lines of the wheel wells much more clearly outlined in the Audi R8 and combines them with the top edge of the vehicle body. Especially when viewed from the rear, the Audi Spyder Concept e-tron seems even more strongly and more strongly oriented horizontal to the road.

The contrast of materials is reminiscent of a racing car. The essential functional elements of the chassis and vehicle body are made of carbon, while the body as a sports deck of a classic paint finish. This illustrates the formal “shell and core” principle that defines the e-tron Audi Spyder Concept clearly identified.

Thanks to an opening in the hood, while the TDI longitudinal study with central motor technology is a visible element surrounded by matte and shiny surfaces of carbon, aluminum and leather. This combination of materials attached outside the vehicle interior.

Behind the seats are two hoods that give way gradually taper towards the rear and side of the opening for the TDI engine and the cooling fins implicit motor housing. They also contain anti-roll bars normally hidden, that as in the production R8 Spyder triggers within milliseconds and take up position in case of an emergency.

Interior:

Visual and functional reference to the basic concept of lightweight construction characterizes the interior design purist. Establish a connection between genes and tested Audi new formal identity. Typical for Audi design language is the reduction of architecture, and output controls to the essential information for an overall impression ordered.

The thin board has a curve that extends laterally into the door panels. No need to allow transmission, shifter and driveshaft tunnel, new designers took the opportunity to create a central tunnel especially thin and light and convex, arching the center console to the e-tron Audi Spyder Concept powered hybrid.

The only other element of control that the MMI is the selector lever for automatic transmission flush, which extends upward from the tunnel when the vehicle is started.

The cabin of the Audi Spyder Concept e-tron is also oriented toward the driver – a special characteristic of Audi. Instead of the classic instrument panel, the concept car is equipped with a large screen, with integrated MMI and flanked by two disks. The MMI can be controlled through a control panel touch on the wheel – an item inspired by the modern smartphones.

Can also be controlled via the MMI control unit (MMI touch) in the center console. The wheel itself is clearly out of flattened top and bottom, in a clear reference to motorsport. The speed is displayed digitally. The online tool with information on the drive system can be chosen through the menu option “Drive.”

In addition to information about the speed, the revolutions of the combustion engine and electric motor, the center display also offers all the key information infotainment and navigation systems.

Feature to the design of e-tron Audi Spyder is the virtual elimination of switches and components such as the ignition. The climate control unit is located right above the steering wheel. The display provides information about temperature and ventilation. Again is based on a smart phone, the system is operated through a control panel touch.

The seats also lightweight racing-inspired bucket combines excellent lateral support with comfort. The contrast of colors and stitching define the different areas of the interior. The colors and quality materials combine elegance and sportiness.

Engines and transmissions:

Audi has always demonstrated the perfect synthesis between a sports car very advanced TDI technology. With the TT, Audi emerged as one of the first manufacturers anywhere in the world to successfully bear a diesel sports car market, a decade after the Audi Cabrio paved the way for diesel engines in this segment.

And the Audi R8 TDI Le Mans concept car was the first supercar to be equipped with a twelve-cylinder diesel engine with 500 hp and 1,000 Newton meters (737.56 lbs-ft) of torque.

The e-tron Spyder Audi also uses this recipe for success – albeit in a revolutionary new combination. This marks the first use of a new generation of six-cylinder 3.0 TDI, breathing through two turbochargers and produces 221 kW (300 hp). That is another 50 horsepower more than the previous stage, which premiered earlier this year in the new Audi A8.

The maximum torque of 650 Nm (479.42 lbs-ft) is unusually high, even in the sports car segment. The longitudinal mid-mounted 3.0 TDI engine drives the rear wheels through a dual clutch transmission speeds of seven.

Another innovation is the coupling of the TDI with the electric motor axle. Two electric induction motors with a total power of 64 kW (88 hp) and maximum torque of 352 Nm (259.62 pounds-feet) combined with giving the Audi 3.0 TDI e-tron yield Spyder sports car high performance. Accelerates from 0 to 100 km / h (62.14 mph) in 4.4 seconds. Top speed is electronically limited to 250 km / h (155.34 mph).

Noise level low speed TDI is typically low. The six-cylinder unit behind the occupants sports grunt loudly under load, but never becomes loud. A surprising effect is also present in the Le Mans-winning Audi R10 and R15 race cars, which are also equipped with TDI engines.

The benefits of this particular form of hybrid drive – the connection of a high torque and high efficiency of the TDI engines with electric motors – are by no means limited to the dynamic potential of e-tron Spyder Audi, however. The opening of two seats also sets new standards in its class for fuel economy and environmental characteristics.

The TDI uses 300 horsepower on average just 2.2 liters of diesel per 100 kilometers (106.92 miles per U.S. gallon), which corresponds to CO2 emissions of just 59 g / km (94.95 g / km).

The full hybrid e-tron Spyder Audi has also dominated the discipline of driving without emissions. In residential and other urban areas, the driver can activate the electric motor itself. 9.1-kWh battery in front of the car has enough power for up to 50 kilometers (31.7 miles). And with a top speed of 60 km / h (37.28 mph), the e-tron Audi Spyder Concept is also able to move along smartly in city traffic.
