First Drive: Volkswagen 3L TDI

It wasn’t long ago the European thought the idea of a regular vehicle that consumes 3 of fuel for every 100 kilometers was a pipe dream. A challenge was put out to car manufacturers to produce such a and former VWAG Chairman Dr. stepped up to the plate and swung — he usually didn’t too many pitches when it to engineering feats. What is the Volkswagen Lupo 3L TDI, the first 3-liter consumption car.

Positioned below the in Europe, the Lupo is the lowest Volkswagen model available At first glance though appearances can be very deceiving. The has an enormous green house makes the car appear very Its width appears fairly as well and gives the Lupo an decent stance. Until you at the profile, particularly with the end to sheet metal behind the wheels, you then realize how the Lupo is in length. Overall if you put the Lupo next to a new Mini the Mini would appear at first glance due to packaging

With round projector headlamps and a slippery smooth end designed to cut through the wind, the has a very meek appearance is altogether feminine but somewhat at the same time, owing to the basic looking wheels and of any exterior frills — was the most frequent comment if anyone even noticed us.

So the Lupo won’t get you noticed, it however bring serious credentials in the economy department. A consumption vehicle roughly into about 78 miles per of diesel — pretty impressive and a first for any manufacturer. So how did do it? How much time do you have?

Three cylinders, balancer direct injection with injector system, turbocharger variable turbine geometry, air cooling, minimized frictional in the valve gear, bearings and and even an aluminum alloy block: The development engineers in pulled out all the stops on this The result: the three-cylinder TDI achieves the efficiency world-wide for an engine of type.

The 1.2-litre three-cylinder under the hood is the first engine from Volkswagen the first diesel direct to have not only its cylinder but also its cylinder block in At just 220 lbs. the three-cylinder TDI is one of the lightest diesel power for passenger cars period.

of inherent design issues a three cylinder design, used a balancer shaft to vibrations and the result is an extremely engine. Injection is via pumpe high-pressure unit injector arranged in the cylinder head and by the camshaft. The higher pressure a more efficient burn improved performance and economy.

The TDI also utilizes a Garrett with variable-vane turbine At high revs and high the duct directing the exhaust gas the turbine blades forces the blades open to increase Correspondingly at low-rpm’s the vanes to produce a smaller surface with virtually no lag — it is like having two turbos in one

The 1.2-liter TDI has an output of 61hp and a torque of 140 Nm (103 lb-ft) is between 1,800 and 2,400 A pre- and main catalytic together with exhaust keep pollutant emissions to an extremely low level.

While the above power don’t give a good impression, keep in mind the weighs in at only 1,882 lbs over 1,000 lbs. than a Golf 1.8T. to Volkswagen the top speed of the Lupo 3L TDI is 165 (102 mph) and acceleration 0 to 100 km/h (0-62 mph) 14.5 seconds. The engine is not unusually refined, but also has thrust. Volkswagen claims the Lupo 3L can actually do better 3 liters per 100 kilometers of consumption, we were not able to test as we were limited to 3 days of driving since the low-sulphur required for this car is not available and VW only had limited supplies. we never saw less than 68 per gallon during all our around driving — pretty

Fuel consumption as low as this to a problem in colder months: Not fuel is burned to provide heating for the passenger compartment. planned ahead though an electric auxiliary heater can pick up the slack where the system can’t.

At the time we the Lupo, we were aware it had a strange new transmission, but what VW tell us till now is that it is in the new direct shift gearbox found in the R32 and Audi TT 3.2, with very different and one less gear.

In simplest DSG is a dual-clutch electronically controlled similar on the outside in appearances to a automatic, but more like a gearbox mechanically inside there is no clutch pedal. DSG 2 clutches, 2 main input and 2 sets of gears — 3rd, 5th and Reverse on one shaft and 4th on the other. What you see in the car looks similar to a regular tiptronic with P, N, and E (for economy of drive) and a gate to the left for shifting.

Drop the transmission into the E and it behaves very much an automatic transmission except the transmission always selects, of accelerator position and speed, the conditions of the engine which are favorable for optimum fuel When you come to a stop the goes into neutral and 4 seconds of sitting the engine is down automatically. Lift off the and the car fires right back up and engages the clutch. A switch on the will defeat the automatic and stopping of the engine and adjust the program to something a little if you need it. While driving if at any the car is coasting the transmission will go into neutral and the engine back to idle to minimize losses and optimize economy. All of is seamless in operation and actually easy to get used to since it no effort on the part of the driver.

In direct shift has clear The engine is started with the pedal depressed and the selector in Park. In position E the car drives off the accelerator is depressed, and the driver can between the Economy and the automatic by means of the switch mentioned The battery and starter motor been beefed up, to cope the frequent starting. The latter is to handle more than starts.

So the next question is what of diet did Volkswagen put the Lupo on to get the down? Practically all external parts are different than the Lupo in terms of material and elements of the structure under the have also been

The front fenders, doors and are made of aluminum as are many components. Aluminum is used for the frames, and magnesium for the internal of the steering wheel. Aluminum is used for the firewall, which the bulkhead between the engine and compartments. The frame itself has been changed to high-strength steel, which meant the wall thickness could be

Altogether 110 lbs. of weight has saved on the body alone- any sacrifices of torsional stiffness, life or safety according to With full-size airbags, restraints on all four seats, safety steering column and protection elements in the doors, the 3L TDI possesses the same safety as all other Lupos. It even has ABS electronic brake pressure as standard.

Smaller cooling air in the front bumper, a streamlining of the rear wheel spoilers, the flat underbody and the rear extended at the top all help aerodynamic with a cd of 0.29 which is good for a hatch.

The suspension of the Lupo 3L TDI — McPherson at front, torsion beam arm axle at rear — been largely redeveloped in the of weight. Through the use of mostly components more than 132 of weight have been on the running gear.

At front the damper struts, the the engine subframe and the brake are of Aluminum On the rear axle, the arms have been in steel. Coil springs and the latter in Aluminum, have separated as on the base model this separation giving room in interior hatch The rear drum brakes are Aluminum

The forged alloy of the Lupo 3L TDI not only have a advantage, but also a visual They carry low rolling tires (155/65R-14). Their consist of light Aramid These, together with the technology for the tread, reduce resistance by some 30 per cent to Volkswagen.

Furthermore, springs, shafts, brake servo, and steering column have weight-optimized. Even the gas-filled which support the opening of the hatch and engine bonnet been lightened, being largely of Aluminum

The spare has been replaced with a can of and an electric air pump although is room for a spare tire if you can to add the additional weight!

All windows are of tinted glass, which for of weight saving is thinner normal. This alone 6.8 lbs.

In its interior equipment the 3L TDI is anything but a frugal economobile: The doors have a sturdy the seats are upholstered in the same as the most upmarket Lupo All seats have adjustable restraints, and the rear seats Isofix mountings for two children’s

The dashboard has speedometer, rev counter, gauge, clock and an on-board — this latter displays both instant and fuel consumption. The gear is also displayed.

Typical Volkswagen attention to detail is shown even at level with folding grab handles, sun visors integrated make-up mirrors, rear seat backrest can be fixed in two positions, numerous areas and chromed tie-downs in the area.

Overall the still has a lot to offer even its obviously small-size and basic exterior. Passenger accommodations are good up front and decent in however hatch space is at a big — two bags of groceries fit next to each other.
