Turbocharging produces a maximum torque of 160 Nm (at 1,400 to 3,500 rpm). 1.2 TSI 77 kW The improved performance version of the 1.2 TSI Green tec, which includes a start/stop system and brake energy recuperation, manages an output of 77 kW (105 hp). This TSI engine provides a maximum torque of 175 Nm at between 1,400 and 4,000 rpm.
The Mark III Polo or Typ 6N, (sometimes referred to as the "Mark 4" by enthusiasts as it is the Polo's fourth guise) appeared in 1994, [1] [10] and was a completely new model (on a new chassis), available as three- and five-door hatchback versions, the latter making VW the last major European manufacturer to finally offer rear side doors in ...
The end result is a car capable of producing less than 100g/km of CO 2 with a stated fuel economy of 74.3 mpg (3.8 L/100 km) on a combined cycle. Volkswagen plans to use the platform set by the Polo on expanding their BlueMotion ranges which include the Volkswagen Golf and the Volkswagen Passat.
The crankpin connects to the larger end of the connecting rod for each cylinder. This end of the connecting rod is called the "big end", as opposed to the "small end" or "little end" (which connects to the wrist/gudgeon pin in the piston). The bearing which allows the crankpin to rotate around its shaft is called the "rod bearing". [5]
The Rapid petrol automatic also lacks a DSG and uses a more traditional 6-speed torque converter instead. Since April 2012, the car has been sold in Malaysia under the name "Polo Sedan". The car is also manufactured and sold in Russia and Thailand as "Volkswagen Polo Sedan" with only the petrol engine available.
The torque tube design is typically heavier and securely ties the rear end together, thus providing a rigid rear end and assuring good alignment under all conditions. However, because of the greater unsprung weight of the torque tube and radius rods, there may be a "little hopping around of the rear end when cornering fast or on washboard roads ...
The MK3 Polo was unveiled on 31 August 1994, and was immediately available in left-hand drive form for continental markets, [9] and was launched on the right-hand drive UK market in October that year. It was the first completely new Polo to be launched since the MK2 model in 1981; although that model had undergone a major restyle in 1990.
Typically, the big end connects to the crankpin using a plain bearing to reduce friction; however some smaller engines may instead use a rolling-element bearing, in order to avoid the need for a pumped lubrication system. Connecting rods with rolling element bearings are typically a one piece design where the crankshaft must be pressed together ...
