VW 3-cylinder diesels
Featuring Polo 1.4 TDi and Lupo 3L
HIS ISN’T THE FIRST THREE-CYLINDER diesel in modern times – Daihatsu had one under the bonnet of the Charade in the early eighties.

In 1.2 litre/61bhp guise, installed in a special version of the Lupo(not yet on sale here inthe UK), VWclaims that its fuel consumption will average 3 litres per 100km (i.e. 94½ mpg) in the official tests – hence the title Lupo 3L(itre).
To achieve such frugality, VW has virtually reconstructed the model, so that although it looks similar to any other Lupo, in fact it bristles with ingenious (and expensive) solutions to reduce weight and ensure ultimate mechanical efficiency. The use of aluminium, plastics, even magnesium in the body and chassis has produced a formidable weight saving, compared with an equivalent, regular-series Lupo 1.7SDi, and its aerodynamic efficiency has improved from a Cd value of .32 to .29.
However, it’s the under-bonnet wizardry that plays a major role. As well as the direct-injection three-pot
turbo-diesel, the “conventional” five-speed synchromesh gearbox is also electronically controlled, it uses hydraulics to do the shifting, so it finishes up behaving like an automatic, with an additional “Tiptronic” manual shift facility when required.
Even the automatic shift sequence has dual modes – for ultimate fuel economy, an Eco button on the facia is depressed, which results in very early upshifts (1800rpm on half-throttle compared with 2800rpm in non-Eco mode), plus two other features. These are a freewheel on the overrun (like being in neutral) and the engine switching off a few seconds after coming to a traffic halt – if the footbrake stays depressed. The traffic-lights turn green, you release the brake and the engine starts again, with gentle “creep” (just like a conventional automatic) in gear.
We found the early upshifts embarrassing at times (when it changed from first to second half way across the traffic, emerging from a junction, for instance) and the shift quality can be rather ponderous, especially when taking off from rest.
In non-Eco automatic guise, these “special effects” don’t occur and if you prefer a clutchless manual car,
