Body

Audi has created an intelligent combination of various materials, rendering the body of the new Audi A6 extremely light, safe, and stiff. Thanks to its composite steel-aluminum construction, the body weighs approximately 15 percent less than a conventional steel construction, earning the sedan with the four rings a top ranking among the competition. Providing 130 kW (177 hp) of power, the Audi A6 2.0 TDI tips the scales at just 1,575 kilograms (3,472.28 lb), not including the driver.

Aluminum components make up more than 20 percent of the body. The strut mounts at the front of the car are castings; the struts in the engine compartment and the crossmembers behind the bumpers are sections made of this lightweight material. All add-on parts, such as the front fenders, the engine hood, the rear hatch and the doors, but also the bulkhead and the crossmember in the luggage compartment, are made of aluminum panels.

High-end steels also play a key role in the new Audi A6. The best of these are the hot-shaped steels, which get their extreme tensile strength from a temperature increase during the shaping process. These steels are found in some areas of the passenger cell and at its transition to the front end of the car. In many areas, tailored blanks are used. These are panels of various thicknesses that are thicker and stronger in areas subjected to higher loads.

The new Audi A6 sedan is extraordinarily quiet. Thanks to a sophisticated aeroacoustics system and extensive insulation, the noise level in the interior remains very low even at high speeds on the highway. The excellent vibrational comfort is the result of painstaking tuning of all components, systematic hydraulic damping in the axle and drivetrain bearings, and the extremely stiff body.

The precision aerodynamic tuning, which also includes the paneled underfloor and the airflow through the engine compartment, translates to a drag coefficient (Cd) of 0.26 in the base version, an improvement compared with the predecessor. The frontal area of the new Audi A6 measures 2.3 m2 (24.76 ft2).

Headlights

The headlights give the A6 a distinctive look. Featuring a shallow design that becomes wider toward the fenders, they shift the visual focus outward. A curved panel, or wing, gives structure to their interior, and the bottom edge forms an undulatory contour.

High-intensity halogen headlights are a standard feature on the new Audi A6. Xenon plus units that include new all-weather lights and an LED daytime running light strip are optionally available from Audi. Also available is the adaptive light function, which ensures just the right illumination in all driving conditions. Among its features is the floating headlight range control system, which detects other vehicles and localities with a camera and adapts its own light by swiveling the modules with soft transitions.

The headlight control unit works together with the optional MMI navigation plus system, from which it obtains route data in advance. Using navigation-based vehicle assistance, the system can activate the highway lights while the car is still on the on-ramp, for example, or turn on the cornering light even before the car reaches an intersection.

The new A6 can also be outfitted with all-LED headlights - a major technological innovation from Audi. The white light they emit is similar to daylight; at night, it is gentler on the eyes. The LED headlights are long-lasting, maintenance-free, and highly efficient; at low beam, each unit requires just 40 watts of power.

The high-performance LEDs for the low-beam and high-beam headlights produce striking graphics. The daytime running lights and turn signal, comprising a multitude of LEDs, appear as a homogeneous strip at the bottom edge of the headlight. The high-beam assistant switches automatically between the low and high beams. The cornering light, the all-weather lights and the highway lights round out the system.

2010 Cadillac Urban Luxury Concept wallpaper

Cadillac Urban Luxury Concept has its world premiere at LA Auto Show. It is a design study exploring a new type of vehicle that offers a luxury experience in a diminutive size which compact dimensions with the design, features and technology for which Cadillac is known.

It has a small exterior footprint, but is roomy inside to popular city cars found in Paris, Shanghai and London. Engineers have developed a concept hybrid propulsion system for the Cadillac Urban Luxury Concept that includes a turbocharged 1.0L three-cylinder engine employing electric assist technology, engine start-stop function, brake energy regeneration and a dry dual-clutch transmission. Based on extensive prototype and production experience, a combination of these technologies could offer projected fuel economy of 56 mpg in the city and 65 mpg on the highway.

Using the 19-inch wheels are pushed to the edges of the body – a design that creates almost no overhangs, leaving more space inside. In fact, the car’s wheelbase is 97.1 inches (2,467 mm), but the overall length is only 151 inches (3,835 mm). The interior room is bolstered by a wide, 68.1-inch (1,730 mm) stance and 56.9-inch (1,446 mm) height.

2010 Cadillac Urban Luxury Concept’s interior offers modern parents a conveniently integrated Orbit Baby SmartHub, a large windshield and twin skylights. Also includes a pair of projected readouts flanks a large, prominent analog speedometer reminiscent of a high-end time piece, assisted by a high-definition head-up display. Capacitive multi-touch switches throughout the interior ensure seamless and intuitive electronic control.

The Urban Luxury Concept’s interior materials convey luxury through quality and advanced technology. Blue and grey leather dominates the interior space and is contrasted by fabric selected for its high-tech look and feel. It is finished with carbon-color wood inlays, brushed aluminum accents and ceramic materials. Ambient lighting conveys an upscale aura that is complemented by the ultra-modern Tanzanite glow of the touch-screen displays.

Heavy Hauliers * UK - Raised Speed limit for

The speed limit for ultra-heavy loads will increase from 12mph to 25mph this week

London,EN,UK -Road Transport, by Roger Brown -29 November 2010: ... The Department for Transport (DfT) says the change - due to come into force on 29 November - will apply to artics weighing between 150 and 250 tonnes... For draw-bar trailer vehicles weighing between 150 and 250 tonnes, the limit will increase from 12mph to 20mph... Girder frame trailers will remain restricted to 12mph... About one hundred abnormal loads weighing in at more than 150 tonnes are transported each year... However, according to the DfT, technological advances in the vehicles and trailers concerned mean that it has now been possible to revise the speed limits... Research into the changes was carried out on behalf of the Highways Agency last year, followed by a consultation process with the industry... It suggested that despite most abnormal loads being transported outside of peak times, the cost to the economy as a result of the congestion caused was about £5.1m per year... By increasing the maximum permitted speed of certain loads, the figure is expected to fall to £2.5m... The research also showed the increased speed would have only a marginal impact on wear and tear on the roads... Police believe the move will also reduce the number of accidents caused by traffic crashing into slow-moving loads from the rear...
