Mercedes CLA aerodynamic testing

Mercedes CLA is the most aerodynamic production car of the world

With a drag coefficient (Cd) value of 0.23, the CLA sets a new benchmark – both within the Mercedes-Benz model range and among all production vehicles. The drag area, Cd x A – which is crucial to aerodynamic resistance – also leads the field, at 0.51 m². This record figure is undercut still further by […]

Application example of free form screen

A new prototype car display system developped by Mitsubishi Electric

The system’s free-form screen responds flexibly to the increasing use of curves and other design features in car interiors. At the same time, its easy visibility helps to promote driving safety. The system incorporates display technologies that Mitsubishi Electric fostered through its development of rear-projection TVs as well as car electronics that withstand severe operating

The continuously variable transmission (CVT)

The variable diameter pulley CVT A CVT transmission consists of a driving shaft and a driven shaft, each of which has a pulley splined onto it. Each pulley comprises two conical sheaves that face each other. A metallic pushbelt runs in the V-groove between the two conical sheaves of each pulley. The pushbelt (See glossary)

Glossary automatic transmissions

ATF: Abbreviation for Automatic Transmission Fluid, which is the lubricating and hydraulic oil used in the automatic transmission. Belt: On a belt-type CVT, the belt is stretched over two pulleys to transmit torque. There are belts that incorporate steel elements, as well as those that come in chain formats. CVT: CVT refers to Continuously Variable Transmission. This

Dual Clutch Transmission market trends in Europe

In Europe, the majority of transmissions are manuals, but the increasing efficiency and shift feel of many non-manual transmissions is resulting in a slow move away from manuals, as people discover the convenience they can offer. Dual Clutch Transmissions (DCT) in particular are quite efficient, so they form part of this growth, although in many
