VOLKSWAGEN is finally pensioning off its long-serving 1.9-litre TDI diesel.

The car that really gave the modern diesel credibility has had a good innings, but it’s now being put out to pasture, after driving (almost) billions of VW Group cars off the production lines.

TDI earns its place in historyIt’s been around in the Golf since 1994, after production was slowly ramped up in the Audi 80. Coming to the Golf was big-time for this then-startling new powerplant; because, unlike its rivals, Volkswagen had mated 1896ccs of blown four-pot to direct injection.

Controversial, this was, at the time. Direct injection is noisier and rattlier than indirect, you see; every single driver who’s experienced the 1.9-litre’s characteristic rattle ever since will attest to that.

The benefits, foresaw canny old Volkswagen, come in more compact combustion chambers. These lose less heat to the surrounding coolant – which, VW reckoned at the time, equals a 15 percent efficiency saving.

It was punchy. 90hp at 4000rpm was superb for 1994 – particularly in the 1145kg Golf (yes! I had to double-check: 1145kg, for the ‘heavy, safe and solid’ MkIII Golf? Now, a Clio weighs more…). This saw it to 60mph in 11.5secs; fast enough to have Autocar & Motor asking when the GTi-bodykit version would arrive. (Seems they were ahead of their time, too).

But just as impressive was the 149lb/ft torque output, particularly as it came in at just 1900rpm. This, remember, was before the days of PD pump-jet injection; the 1.9-litre TDI’s trademark low-rev surge is an inherent trait, it seems. It’s a damn strong engine from the innards out.

OK, said Autocar & Motor, the tickover is ‘boisterous’, which may put some off. Back in those diesel-pensive days, it more than likely did. A £2k price premium over oil-burning French rivals didn’t help its cause, either. But, such it always is for VW.

This couldn’t dim the significance of a fine engine, though. Even its first mainstream installation saw it mark itself out as special. Evolution through the years, particularly in the MkIV Golf, underlined its place in history.

Will its replacement, the 1.6-litre TDI, be as venerable? Time will tell. For now, though, here’s a cup of oil to a diesel that I’ve seen, through car magazines, develop, delight and dominate. Classic Diesel, here’s your first-issue feature car…
