Locomotive

A man whose car the device is of little interest, which only need to move quickly and comfortably from point A to point B, the numbers 400/1400-3250 in the section "torque" is probably not say much. But, oddly enough, that such people exist and A4 with the 2.7-liter turbodiesel "six" and stepless variator (from the column as "transmission"). These two can get the same locomotive. Which does not catch it, jerking on acceleration ... He just picks up speed. Audi is the same. Only much faster. Acceleration to "hundreds" fit in eight seconds. And what is the acceleration! From the bottom - line, straight off! The work of the variator is almost imperceptible. More precisely the opposite - visible, for it is not least thanks to the smooth change of gear ratio made possible such an acceleration. There is a feeling that the car pulls the rope some huge invisible ruchischa. Capacity of 190 "horses". But in fact this "herd" hiding under the bonnet drives the front wheels - Audi CVT in gets only with front-wheel drive. "Horses" are very quiet - no noise, not hooligans, not in vain neigh. Only at idle give themselves a soft muted tarahteniem outside and barely noticeable vibration inside. Soundproofing the engine is so good that in the cabin of his voice in all modes is almost inaudible. All that is required from the driver, it put pressure on the gas. I tried to play with the manual mode of the variator, which allows you to choose one of eight psevdoperedach. Children's pranks! Lead nowhere, except jerks when changing levels. You lose the main advantage - the smoothness of acceleration. The main advantage and - the main enemy of the active driver. Quickly, reliably, safely, with a huge stock of traction at any time, but boring. Not everyone wants to go because - like in the electric vehicle. But may change their minds after looking in the column "economy." During the test, in a very active drive, the average consumption was 12.5 liters per 100 kilometers. Petrol V6 of just under 3 liters missed the 20 liters per hundred in the same conditions. And the dynamics of cars is absolutely comparable, though dispersed in different ways. Nuances of behavior for the machine meets the mode switch the transmission, engine, suspension and steering. We can not say that three of its provisions - Comfort, Auto and Dynamic (there's Individual, parameters are set independently by MMI) - is made from three different Audi car, but the effect of the inclusion of this key still is. Especially on the steering wheel and on the response to pressing the accelerator. The "comfort" cake turns very easily, the reaction of the gas strongly zadempfirovana; in the "dynamics" is poured into a steering wheel turns the weight, but after hitting a whip hiding under the hood "horses" were instantly transformed into a gallop. On the suspension of the changes seen less. Audi at the 17-inch wheels have an excellent balance between comfort and sportiness in all modes. Mode switch is only slightly shifts the balance in one direction or another. Extremes - no sports car, or limousine of this Audi A4 after pressing the button does not work. Most of all I liked this combination: engine, CVT and the steering wheel - a Dynamic, and suspension - in Comfort. The car is not shaking, she jumps on bumps, but on the handlebars, in contrast to the Comfort mode and Auto, there is a tangible force, and the engine and CVT "locomotive" in full. A great option for longer trips on country roads where you have to shoot powerfully for overtaking, and coverage is not always perfect. In general, control here, as well as dynamic, robust, confident, but without the spices. Too far at the entrance - the projected demolition. Reduced gas - went inside. Skid be difficult. And ESP is on guard, preventing slippage or movement sideways in the bud. Trumps of the "quartet" - the ideal smooth acceleration and good fuel economy. Temperamental to be called, despite the excellent dynamics and a tight suspension. If you want it hot, it's better to look at other modifications A4. Maybe even the "stick". But for the "easy ride" - better than you can imagine. By SVEDENIYuNovoe generation motor 2.7 V6 TDI - another round of evolution. Compared with the engine of the same volume of past years a new more powerful on high-torque 10 hp and 20 Nm. Each cylinder has four valves. Fuel injection system - common rail, and has variable geometry turbine. Exhaust satisfies Euro-5. Compared with older, 3-liter turbodiesel V6, the volume is reduced due to a shortened stroke (83.1 instead of 91.4 mm) with a constant diameter. Less volume - better efficiency (6.6 vs. 6.8 liters per hundred).
