First VW Polo BlueMotion to have gasoline-fueled TSI technology; new 3-cylinder engine, 57 mpg

Volkswagen is introducing its first fuel-saving BlueMotion vehicle with a gasoline-fueled TSI engine with the Polo TSI BlueMotion. (Earlier post.) Improvements to the TSI engine management system have made it possible to reduce fuel consumption by a further 0.2 liters to 4.1 l/100 km (57 mpg US) and emissions to 94 g/km CO2.

As a result, the TSI BlueMotion is the first gasoline-fueled Polo to receive a class A label for energy efficiency and achieve top ratings for fuel consumption and CO2 emissions in its class.

The new three-cylinder engine with a displacement of one liter delivers 70 kW / 94 hp and can reach a top speed of more than 190 km/h (188 mph).

Apart from this first use of the highly efficient engine, the fuel consumption figures were also the result of lowering the ride height and improving the aerodynamics over the radiator grille and the underbody.

Furthermore, the Polo TSI BlueMotion also benefits from reduced rolling resistance tires and longer gear ratios in the upper transmission stages. Other factors contributing to greater driving economy are the stop/start system, regenerative braking and a gear-change indicator for the driver.

A new electro-mechanical servo steering system improves steering properties. Assistance systems have also been introduced into the Polo program such as the standard Automatic Post-Collision Braking System (which automatically initiates braking after a collision) and the optional Driver Alert System, Front Assist ambient traffic monitoring system with City Emergency Braking and Adaptive Cruise Control (ACC).

The infotainment options have also been re-conceptualized, with three radio/CD systems and one radio/CD/navigation system. Depending on the version, the devices offer functions such as Bluetooth audio streaming (including cover display and touchscreen control, depending on the smart phone used), a proximity sensor (other menu details are shown when hand approaches the screen), and interfacing of the mobile phone to the vehicle’s exterior antenna by inductive coupling.

The entry price for the new Polo TSI BlueMotion is €15,925 (US$19,800).

Actually, 190 kph = 119 mph,not 188 mph, but plenty fast enough. This is great, more 1-liter turbocharge engines for hybrid and PHEV makers to choose from to make the next gen hybrid and PHEV. I have yet to see a 3-cyl-1-liter turbocharge HEV nor PHEV, but these engines offers real advantage. Add a 3-speed transmission and a modicum 40-60-hp motor and one will have a low-cost HEV setup yet offering exciting and fun to drive with excellent acceleration.

"The entry price for the new Polo TSI BlueMotion is €15,925 (US$19,800)"
Well, with hybridization as above, add about $3,000-4,000 to the above price, to get $22,800-23,800 to arrive at the cost for the HEV version. Not bad.

You can't really believe the mpg figure if they were got using the NEDEC test, but if it says 57, it might work out at 45, which is still pretty good.

Have to see what independent testers come up with.
Also nice to see a non-diesel BlueMotion car.

This is probably a very nice car and will get good mileage but as mahonj points out it will not get 57 mpg in the real world. The US (EPA), Europe, and Japan need to get together and have consistent mileage testing that is somehow close to what people could expect to get with normal driving. The US (EPA) ratings are probably much better than either the Japanese or European ratings but they have also had problems (and some deliberate cheating).

IMHO, these MPG standards are solely meant for consumers to compare relative efficiencies of different car models, and NOT as predictions of real-world MPG numbers. That they are higher than real life average mpg is actually a nice thing, because they reflect mpg's achievable by careful and efficiency-conscious drivers. This is because only efficiency-conscious drivers actually care about looking at a car's MPG rating, while lead-footed drivers could care less, so the mpg standards actual can reflect a subset of efficiency-conscious drivers. I routinely achieve 5-8 mpg's higher than EPA's number on the Prius and 3-5 mpg's higher on non-hybrid models, so I do not appreciate EPA numbers as being reflective of the mpg's of those who would care to look at the MPG ratings the most.
