Jaguar has unveiled its most powerful open-topped GT ever on the first day of the Los Angeles Auto Show.

The automaker took the wraps off the XKR-S Convertible November 16, describing the model as a “new performance echelon” at the top of its XK range.

Boasting a 5.0-liter supercharged V8 engine, the model tops out at 300 km/h and manages 0-100 km/h in 4.4 seconds, the fastest time for a convertible Jaguar GT.

Auto Motor und Sport reports that the Bugatti Galibier has been delayed until 2015.

The Bugatti Galibier is still in the works but the model being develop differs substantially from the concept we have previously seen.

The group has been taking advice about the Galibier’s design from current Bugatti owners, with half of those who own a Veyron having already been inside the new car.

Bugatti chief Wolfgang Durheimer told Autocar that the Galibier is still in development and “in its second half of the design phase.”

Hailed the world’s most expensive and precious car model by Guinness World Records, this creation is based on the Lamborghini Aventador LP 700-4.

The car was crafted by Robert Gülpen — who has also created miniatures of the Mercedes Benz 500 SL and Aston Martin DB5 from precious metals and gems.

The Lamborghini is made from carbon fibre like the original and its shell was milled using computer modelling data handed over from the Italian car manufacturer.

Ferrari officially released today the first images, together with all the details and a video of the new open-top, Ferrari 458 Spider.

The top is made from aluminium, achieving a 25 kilogram weight reduction over the previous system, and Ferrari says it can be raised or lowered in 14 seconds.

Power is supplied by the same 4.5 liter V8 unit from the 458 Italia coupe which delivers 570 PS (425 kW / 563 bhp) and 540 Nm of torque (398 lb-ft).

Infiniti is to team up with a group of leading chefs to add extra elegance to a new concept set to be unveiled as part of the Monterey Auto Week in California.

The Japanese brand is working with Hearst Magazines to showcase the new Infiniti JX Concept, which will be revealed at the 61st Pebble Beach Concours d’Elegance.

As part of the reveal, chocolate, cheese and wine tasting sessions have been scheduled, as well as cooking demonstrations from US celebrity chefs including Tyler Florence, Marc Forgione, and Andrew Carmellini.

Bentley could add an SUV to its lineup. The automaker is said to have discussed plans for a sports-utility vehicle with Volkswagen, its parent company.

Such a model would satisfy appetite for luxury models, reports Automotive News.

An analyst suggested that an SUV bearing the famous Bentley badge may be able to fetch in excess of €120,000, such is the demand among drivers.

Bentley could well be eyeing a gap in the Chinese market, where the popularity of the brand’s handmade €154,000 Continental GT and €250,000 Mulsanne helped it to post a 20 percent rise in sales during the first half of this year.
