Affecting fuel economy just as positively is the speed-reducing layout of the five-speed transmission. 19 percent). The effect: These modifications alone improve average consumption by about 0.2 liters per 100 kilometers. A pleasant additional benefit: A reduction in engine speed level improves noise comfort. The car's acceleration temperament, which is important in everyday traffic, retains its crispness thanks to the engine's powerful torque characteristic and unchanged ratio of the first two gears. However, the greatest influence on a car's fuel economy is exerted by the driver. Besides the efficiency of engine and transmission, air resistance is also very crucial when it comes to fuel economy. The greater the car speed, the greater its significance. As on the Polo BlueMotion, Passat BlueMotion and Passat Variant BlueMotion, on the Golf BlueMotion Volkswagen developers also succeeded in optimizing the aerodynamic advantages of the body by specific refinements. This most prominent visual action: The completely enclosed radiator grille that offers fewer points for the driving wind to take hold.
All other aerodynamic modifications act behind the scenes. Example: Underbody. Special covers for the brake line conduits and trim in front of the rear axle quiet the air stream beneath the Golf BlueMotion and thereby reduce air resistance. Serving the same purpose is the standard sports chassis that lowers the body of the bestseller by ten millimeters. The fuel economy and emissions advantages of the Golf BlueMotion are the result of an entire bundle of different detail modifications that also involve the chassis and tires. Besides the already described production sports chassis that makes for a lower profile by ten millimeters, this savings master also benefits from special high-tech tires with significantly reduced rolling resistance. The Golf BlueMotion stands on 15 inch wheels and 195 / 65 low profile tires. They are driven at air pressures elevated by 0.3 bar and are rated for a top speed of up to 190 km/h (Speed index "T"). As a new option, besides the option of combining the new BlueMotion cars with the first three models - they may also be combined with classic equipment lines. The BlueMotion specifications add to the features of the particular equipment line. This much is clear: When adjustments are made for equipment options, a Golf BlueMotion hardly costs any more than a comparable 105 PS TDI in a classic line.
Cadillacs. The dash and console are accented by wood that actually looks as real and lustrous as it is, and we were impressed by the splashes of chrome on the trim as well. Instruments are legible and straightforward, and most controls are ergonomically correct and intuitive to operate. The exception to this rule are the overhead controls. Three knobs and buttons are present; a rotary knob, and two switches at either side. Take a guess at which does what. The rotary knob doesn't adjust the sunroof as it would in an Audi or VW, but rather it controls the fan's speed for the second and third rows. One of the accessory switches, which looks identical to that fitted to a Chrysler 300 for the sunroof, actually operates the rear windscreen wiper. Only the switch furthest away from the driver's hand operates the sunroof! French stitching on the dashboard is a nice, high-end detail.
