Oil-burning Cadillac CTS captured

No, this isn't a half clapped-out Cadillac CTS. Infact, it's a new diesel version of the CTS undergoing testing on European soil. The oil-burning CTS is being tested on the European continent due to its abundance of engineers with experience of diesel technology and has been thought up to tackle the increasing diesel-powered segment in the States, as well as to offer a viable alternative to petrol CTS models in world markets.

Despite Cadillac trying to get back into the UK market with the BLS which failed, Cadillac could have a good chance with the new diesel powered CTS. The current CTS came in its hundreds into the UK through private importers.

Our source suggests that the 1.9-litre turbodiesel unit used in the BLS is likely not to make the Stateside CTS line-up, with the introduction of Opel's 184 hp 3.0-litre V6 being the preferred powertrain. However, capable of 56 mpg on the combined cycle, the 1.9-litre unit may make a late range entry should the V6 take initial preference. Opel's 3.0 V6 as featured in the Vectra range provides a 41 mpg combined figure.

While the transplanting of the GM stablemate's 3.0 V6 into the CTS is likely, the in-house engineered unit of choice for the firm may very well be a 2.9-litre V6 turbodiesel, premiered at this year's Geneva Motor Show. It was however maintained in an announcement at the show that the 250 hp unit was likely to be sold only in European-spec Cadillacs, taking on Europe's finest with the all-new engine.

Speculation is sure to be rife ahead of the oil-burning CTS' debut, so stay with us for further details.

Please note that the test car pictured above does not have a diesel particulate filter (DPF) which will be standard when the car goes on sale next year

Cold start for Seat

We obtained the first spy photos of the next Ibiza which was caught in the cold undergoing early winter-testing and braking tests. The Ibiza is due to be launched next summer. Following the unveiling of SEAT's Tribu Concept Frankfurt Show star the new Ibiza will be the first production model to adopt the concept's evolutionary styling and begin the shift towards a new design direction for the brand.

Visible through the relatively thinly-applied disguising is the evolutionary new front end of the Tribu in Ibiza form, its trapezoidial layout of grille, headlights and bumper being evident behind the tape. The front lamps are very much the new SEAT's 'eyes', styled straight from the Tribu, while in true marketing speak, the start of its sideline remains its 'eyebrows' all the way to production. The dynamism extends to the rear, but first via a window line side panel crease which rises steeply at the rear door.

The Tribu concept car's rear lamps and hatch arrangement are ditched in favour of conventional, but stylish belt-line lights and hatch door. The new Ibiza gets the characteristic side-flank like its range siblings the Altea, Leon and Toledo although it appears a less prominent re-interpretation of the design feature.

Seen here in five-door guise the next Ibiza like its predecessor will also come in a three-door guise, sedan which will be called "Codobra" and a possibly a cabrio in late 2009. FR and Cupra versions will be available, powered by petrol units offering 150bhp and 180bhp respectively, with diesel units being on offer with 130bhp for the FR and 160bhp for the Cupra. Standard model engines are likely to include options ranging from 70 to 110bhp, with diesel units of 70, 80 or 100bhp being available.
