Lamborghini Sesto Elemento to be produced

According to Automotive News Lamborghini will put the Sesto Elemento concept into limited production. There will be 5 to 10 units built, and like usual the exclusivity has a big price: 2,5 million Euro (almost $3,500,000 at the current exchange rates). Now that the Murcielago is out of production, Lamborghini’s sales will have to suffer, and this decision was made in an attempt to improve the company’s profit that has been hit hard by the global economic crisis.

ZERO-OFFSET STEERING Designed to minimize torque-steer on front-wheel drive cars during acceleration or braking with each wheel on a different surface, the zero-offset steering has a scrub radius of zero. In other words, the lateral forces that act upon the wheels during aforementioned situations are kept to a minimum and the vehicle's stability is improved.

X-Drive all-wheel drive system X-Drive X-Drive is BMW's trademarked name for the all-wheel drive system used on the X5, X6, X3, 3, 5 Series and other future series. Its latest generation employs a multi-plate clutch transfer box situated between the axes to direct the power split between front and rear wheels. Not depending on the ABS sensors alone, like the previous generation, the X-Drive is now controlled by a central ECU which transformed the system from a reactive to an active one. In other words, if just one of the wheels starts slipping the ABS sensors detect it and send the gathered data to the ECU which in turn commands the wet multi-plate clutch trough a high speed electric servo-motor which turns an actuator shaped like a disc. In normal driving mode, the system splits the torque with a 38% - 62% distribution ration between the front and rear axles, but depending on driving conditions it can send up to 100% to a single axle.

WEIGHT-TO-HORSEPOWER RATIO The weight to power ratio is the result of a vehicle's weight divided by the power its engine develops, thus enabling a measurement of performance. WHEELBASE Wheelbase is the distance between the front axle and the rear axle of a vehicle. Cars with a longer wheelbase are more stable at high speeds and provide better interior room, while cars with a shorter wheelbase have better city handling and are generally shorter. WINCH A winch is an externally mounted mechanical device consisting of a cable spooled onto a drum. It is used to pull heavy or bulky objects or to retrieve a vehicle that is stuck in mud. The drum can be driven in a rotating motion by the engine itself, by hydraulic power or even electrically. WINDOWBAGS Like any other airbag, windowbags are designed to protect a vehicle's occupants in case of an accident. They are called windowbags because in the event of a side collision

VALVES A valve is a device that regulates the flow of gases in and out of the cylinders of an internal combustion engine. Intake valves allow the air and fuel to enter the combustion chamber, while exhaust valves allow the burned gases to exit after combustion. Viscous Coupling VCU Viscous Coupling (VCU) can act either as limited slip differential (LSD) or as a central differential in some all-wheel drive vehicles. The device itself consists of two sets of alternating and perforated metal plates mounted in a sealed drum, which are engulfed into a silicone or similar liquid. Each set of plates is connected to a propshaft, and can transmit or limit the power between the two shafts depending on the speed of the plates, which heat up the aforementioned liquid, thus modifying its viscosity. In turn, more or less torque can be transmitted between two axles or two wheels according to the individual speed of the axles (or wheels.) Vehicle Dy

Glossary: U

Universal Joint U-JOINT Designed to transmit a rotary motion between an output shaft and an input shaft with a different angle between them, the U-joint (or Universal) is comprised of two rods (or shafts) connected via a pair of hinges. Unified Chassis Control UCC The Unified Chassis Control (UCC) is a Delphi technology which integrates different safety systems under the same umbrella in order to provide enhanced vehicle control. By integrating systems like the ABS, stability control, traction and even suspension control under a single ECU, the Unified Chassis Control can respond better to unforeseen driving situations. UNITIZED CONSTRUCTION A unitized (also called unibody or monocoque) body integrates the chassis and other structural elements into the construction of the vehicle, and does not require a separate frame or chassis to provide rigidity to the body, thus reducing the total weight.

The New Twelve-Cylinder And The New ISR Transmission

TACHOMETER The tachometer is essentially a gauge that can display an engine's revolutions per minute (rpm or revs). Traction Control System TCS Developed to minimize wheel slippage through turns and low grip surfaces, Traction Control works by using the ABS wheel sensors to detect if any of the wheels is spinning uncontrollably and individually brake it or even reduce engine power until the grip is restored. Turbo Diesel direct Injection TDI TDI is Volkswagen's AG trademarked moniker for their Turbo Diesel direct Injection engines. While in the beginning they were all direct injection engines, now common rail ones also bear the same name in the VAG group.

SEDAN The sedan is the most common configuration of a modern automobile. Sedans usually have four doors, although the term can be used to describe a two-door body also. Most of them have a three-box configuration, but two-box bodies are also common, mostly in Europe. SEMI ELLIPTIC MULTI LEAF SPRINGS Usually found on trucks and sport utility vehicles, this type of springs consists of arched steel leafs that are stacked together horizontally to form the foundation of the rear suspension. SEQUENTIAL TURBOCHARGERS Sequential turbochargers were created from the need to decrease spooling lag. Two or sometimes more turbochargers are put to work in sequence. Usually, a smaller one begins working at low rpms and the other(s) at higher rpms, thus improving the power delivery throughout the power curve, not only above a certain number of revs. SHIFT-ON-THE-FLY Most part-time four-wheel drive systems in the past required their dri

RACK-AND-PINION STEERING Delivering a more precise feel than recirculating ball systems, rack-and-pinion steering is a common type of steering mechanism on modern automobiles. In simple terms, it consists of two gears that convert rotational movement into a linear one. One of the gears meshes with a rack (a toothed metal bar), which in turn is directly linked to the wheels via tire rods. By rotating the gear with the steering shaft, the circular motion converts into a linear one and moving the rack from side to side, therefore turning the wheels into the desired direction. RAMP BREAK-OVER ANGLE The ramp break-over angle measures a vehicle's ability to safely pass over a ramp without touching its underside. For the best break-over angle possible, a high ground clearance together with a short wheelbase are necessary. REBOUND Rebound is the opposite of jounce, so it's still a vertical motion of the wheel. In other words, when

Viper Confirmed!

Chrysler Group LLC plans to bring the iconic Dodge Viper back to its lineup in the summer of 2012. The all-new Viper will be a 2013 model. The Auburn Hills automaker ceased production of the all-American sports car last summer after 18 years. There has been speculation since then that the hiatus would be short-lived and Chrysler would bring the car back.

Porsche, supercar, Detroit

After a four-year absence, Porsche will be making a comeback to the 2011 Detroit Auto Show with a "spectacular new concept that points towards a future road going model." This new concept car is closely related to the 918 Spyder concept from which it takes key components, including elements of its platform. "Porsche’s return demonstrates the relevancy of the Detroit show for luxury manufacturers," said Rebecca Lindland, an analyst at IHS Automotive in Lexington, Mass. "They target a very specific audience with their cars and the U.S. market is incredibly important for Porsche." The German publication, AutoZeitung, suggests that this new model is known as the 929 and that it will be revealed sometime in 2013. A hybrid drivetrain that will combine a 4.8 liter V8 Biturbo engine with three electric motors, something similar to the 918 Spyder, is expected to be found under the hood. "We’ll have something spectacular to show there," H

QUATTRO quattro is Audi's trademarked name for their four-wheel drive system. Now at its fifth generation since it was introduced in 1980 (on the Quattro model, or Ur-Quattro as it is known), the quattro all-wheel drive system is a permanent one, without the possibility of switching from four to two wheel drive. Since on most of Audi's vehicles since the '80's it was designed around a Torsen (torque-sensing) central differential, in case of grip loss on certain road surfaces it can distribute torque between front and rear axles depending on the grip level.

PART-TIME FOUR-WHEEL DRIVE Part-time four-wheel drive is the most common type of all wheel drive. It usually operates only in two-wheel drive mode and it can be switched to all-wheel drive whenever the situation requires. By employing a center differential or a transfer box, these types of all-wheel drive systems can transfer power to either the front only, rear or to all the drive wheels, depending on the driver's wishes. On older designs, the all-wheel drive mode had to be manually engaged and the vehicle had to be stopped in order for the (usually front) wheel hubs to be locked, but it can now be done from the inside of the vehicle and on some vehicles even while they're moving. Permanent Four-Wheel drive PERMANENT FOUR-WHEEL DRIVE Permanent four-wheel drive systems send power to all four wheels in a continuous manner. There is no need for the driver to engage two or four-wheels drive mode, since all of the wheels are always p

4 wheel Electronic Traction System 4ETS Working with the vehicle's full-time four-wheel drive, 4-ETS uses individual wheel-speed sensors to detect the onset of wheel slip. Then it individually brakes the slipping wheels as needed, providing the effect of locking the front, center and/or rear differentials. The 4-ETS system continually balances the torque split to direct power to the wheel or wheels with grip. 4 Wheel Drive and Automatic 4MATIC 4MATIC is the name of a complex electronically controlled all wheel drive system developed and used by Mercedes-Benz on some of its models. All Mercedes cars featuring this system also have an automatic transmission in standard equipment and that's where its name is derived from (4-wheel drive and automatic transmission).
