AZURES3 Posted July 12, 2004 Report Share Posted July 12, 2004 Vauxhall Vectra 1.9 TT Diesel (From Autoexpress) Petrol fans are in for a shock, because the world of performance cars is evolving. In secret workshops across Europe, the planet's biggest motor manufacturers are putting the finishing touches to a new breed of diesel-powered supercars. What's more, the early results are so promising, company bosses are confident that traditionalists can be brought round to embracing oil-burning in the pursuit of driving pleasure. Petrol is fast becoming yesterday's news! This high-performance Vauxhall Vectra Twin Turbo concept, or TT for short, is the first hard evidence of this mysterious development - and Auto Express was first and exclusively behind the wheel to find out what it was like. On paper, the 1.9 Twin Turbo Diesel is very impressive. Delivering 212bhp (112bhp per litre) and a staggering 400Nm of torque, Vauxhall claims that this is the most powerful 1.9-litre diesel ever built. Maximum output is produced from a lowly 1,400rpm, thanks to the engine's twin-turbo design. Yet despite this, the car will still return 47mpg, and meets stringent Euro IV emissions legislation. The key to this amazing combination of thrust and frugality is the use of sequential turbocharging. Employing two different size turbochargers also eliminates turbo lag, making the power delivery smoother. The smaller turbo is in use up to 1,800rpm, then both blowers are on line between 1,800 and 3,000rpm, with the larger unit on its own above 3,000rpm. Auto Express put the Vectra TT through its paces at Vauxhall sister firm Opel's secret proving ground in Germany. The car certainly looks the part - although the lurid blue interior wasn't exactly to our taste, the chunky bodykit and stylish 19-inch alloys certainly were. There's the familiar diesel clatter at idle, but this engine doesn't feel anything like a conventional oil-burning unit. Floor the accelerator from low revs and the power flows very evenly. In fact, the stream of power is so constant - and the familiar turbo kick so obviously absent - that the Vectra's performance feels deceptively mild. It's hard to gauge real-world pace without other cars to measure your progress against, but Vauxhall says the Vectra can hit 62mph from rest in only 6.5 seconds. Engineers say the powerplant will be happy at high revs, too. A favourite trick of the development team during autobahn testing was to cruise along at 70mph, then floor the throttle. They claim that Porsche Boxsters and powerful Mercedes S-Class models couldn't keep up with the Vectra TT's searing pace. Unfortunately, this prototype lacked the final VXR sports suspension package. With only firmer springs and dampers fitted, it wasn't possible to give a definitive verdict on the car's handling potential. However, the front-drive chassis handled the high torque levels well, and only under hard acceleration did the nose get a little light. But the big question is: will we get the car? A spokesman for Vauxhall's high-performance VXR brand told us: "We're discussing the project at the moment. We could go ahead with this 400Nm engine, or wait for a redesigned gearbox, which could then make use of the motor's full 450Nm potential." Either way, it looks as though UK diesel fans are in for a real treat. Hilton Holloway Link to comment Share on other sites More sharing options...
drpellypo Posted July 12, 2004 Report Share Posted July 12, 2004 I hate Vectra's. Am I the only person who thinks that, or is the opinion shared? Link to comment Share on other sites More sharing options...
cheechy Posted July 12, 2004 Report Share Posted July 12, 2004 With performance like that from a diesel who cares how they look! Link to comment Share on other sites More sharing options...
Ari Posted July 12, 2004 Report Share Posted July 12, 2004 Catch them from the right angle and in the right colour and they look quite businesslike... Link to comment Share on other sites More sharing options...

[/ QUOTE ] 100% with you here, they are just so bland, non descript and - with the original at least - shockingly built. I am told the suspension in the current Vectra is nothing short of a joke?! Not even cheap either, a well appointed '148' diesel Vectra is almost 20 Grand! I just don't understand the British public who spend a fortune on a Laguna, 75, Vectra or Mondeo when an Audi, BMW, Saab, Volvo, Lexus etc is a few pounds more. Residuals anyone? Their money I suppose..... Ian C Link to comment Share on other sites More sharing options...
