[Updated with high-res pictures] After the teaser image we showed you earlier today, the first three images of Bertone's design study for a compact Jaguar, hit the web. Dubbed B99 (for the 99th anniversary of Bertone) the eye-catching concept car has a sleek coupe profile, even though it's a four-door sedan. The suicide doors give it a distinctive appearance, but if Jaguar were to build a production model, it's unlikely that they would remain.

While it might look like a long limousine, the Italian design house's B99 concept is just 4.5 meters long. Combine this with the very low height (1.35 meters) and the pretty wide body (1.95 meters) and you have a small sedan looking like a much bigger and more luxurious model, whose profile brings to mind the classic Jaguar XJ.

The very thin A-pillars, the narrow windows and the short front overhang give the car a dynamic yet classy look, while the front and the rear mirror each other, with very thin headlights/taillights and an oval grille whose form is replicated in the back. Inside, the B99 appears to offer a classy environment, mixing brushed aluminium with leather and polished African walnut trim.

Under the hood, the concept sports sedan is said to feature a newly developed full-hybrid drive, but further details remain unknown.

Perhaps best known for its work with models from the Volkswagen Group, Germany's Hofele Design has now revealed a new styling program for the first generation of Jaguar's XK coupe and convertible series built between 1996 and 2005.

The tuner's proposal includes an assortment of body pieces such as the very Aston Marton-like shaped front bumper, optional side skirts, a new rear bumper, a discreet boot lid spoiler, and a pair of round tail lamps with LED units. Also including in the package for the XK are a four-pipe exhaust system and 20-inch "Villa RSV" alloy wheels plus a full leather interior.
