Fast yet frugal, that’s what the technology packed 2012 Volkswagen Polo BlueGT hatchback really is
The Volkswagen Polo BlueGT hatchback showcased at the ongoing 2012 Geneva Motor Show can hit 100 Kph from standstill in under 8 seconds, and go all the way up to a top speed of 220 Kph. Yet, this very hatchback can manage to deliver a mileage of 22 Kmpl. No, we’re not talking diesel engines here but Volkswagen’s turbo petrol engine which comes with direct injection technology and more importantly cylinder deactivation technology, which is mainly responsible for the stellar fuel economy.
The Volkswagen Polo BlueGT hatchback is the first mass market Volkswagen car to feature cylinder deactivation technology, which thus far was a preserve of much bigger engined and much more expensive cars. The Polo BlueGT, which comes with a 1.4 Liter TSI petrol engine pumping out 138 Bhp of peak power is mated to either a six speed manual or a 7 speed dual clutch automatic gearbox, depending on the car buyer’s preference. This car comes with cylinder deactivation technology which deactivates two of the four cylinders of the 1.4 TSi petrol engine ,during periods of relaxed driving or cruising.
The engine’s electronic control unit(ECU) does this by continuously monitoring the driver’s inputs. If the driver is driving spiritedly, the ECU shuts off the cylinder deactivation system and on the other hand, when the driver is cruising at constant speeds with the rpm between 1,250 to 4,000 rpm and torque between 25 to 100 Nm, the cylinder deactivation technology seamlessly kicks in. At any point of time when the driver needs more power and presses on the accelerator, the system automatically restarts the rest of the two cylinders, to offer more power to the driver.
The system operates in an almost imperceptible manner so that the driver doesn’t feel any jerks or non linear increase in power delivered. The Polo BlueGT is also equipped with a start-stop system and brake energy regeneration to further reduce fuel consumption. This car will go on sale in the European market by the middle of this year. Now that cylinder deactivation technology has arrived onto budget cars, expect to see this technology in many more cars in the near future.
