The reports are true: a 3.0-liter diesel Jaguar XK is on the way. The new XK, long due for a serious refresh, will show up in 2009 with the minor addition of the JaguarDrive selector a la XF and the major addition of a diesel engine to boost fuel economy and sales, along with two new V8s.

Since Jaguar's 2.7-liter V6, which puts out 204 hp and 320 lb-ft., is only getting bored out to 3.0 liters it probably won't match the numbers put up by BMW's 3.5-liter, at 286 hp and 427 lb-ft. But the larger lump should goose the horsepower number and seriously increase torque (we hope) at least to the level of Audi's 3.0-liter V6 diesel, which turns out 240 hp and 369 lb-ft.

The next CLK Cabriolet -- or E-Class Coupe Cabriolet depending on Mercedes' choice of nomenclature -- is out and about, wearing lots of camouflage. While this rendering looks like it could still be pretty accurate, the front fog lights have given way to LED's, which are lit in this latest round of images. The extended trunk deck lid we've seen before, but now we get a close-up and the strong crease line that bisects the rear of the car. It also looks to get a bit fussy back there because the trunk is distinct from the body panel that hides the roof.

Fiat took one of its Fiorino vans, chopped off, well, most of it, and dubbed it the Portofino. Supposedly no more than a study for the Caravan Show that starts in Dusseldorf later this week, the golden, buggy-like conveyance is an homage to the 1960s. In a time before Fiat was building $200,000 supercars, coachbuilders were adding open-topped bodies to Fiat chassis like this for fun in the Italian sun.

To stress the beachgoing theme, the Portofino has wood laminate flooring and natural fibers treated with a special waterproofing for the interior surfaces. The car can (optimistically) seat five, and the rear seat folds down for your surfboards and anchors.

Try as we might, we could not find the punchline to this bit of news, so we're going to run with it. Nissan is creating a Murano convertible, supposedly for empty nesters who want a side dish of top down to go with space for the kids and grandkids. Should such a thing occur, it will be searing your retinas as of 2010.

Nothing is slated to change on the car except the use of a soft-top convertible, even less trunk space, and most likely, the price. To see the rendering, if Nissan simply took the top off, the car might be a little bulbous but acceptable. If Nissan were to use a rollhoop, however... that means they're making a PT Cruiser with a higher seating position. And, as far as we're concerned, that just ain't cool... Thanks for the tip, Cory!

While Cadillac busies itself with a 2-door version of the new CTS sedan, the folks over at Coach Builders, Ltd have been busy taking their tops off. The boulevardier CTS gets an insulated, hydraulically-powered roof fitted with a heated glass rear window and cloth headliner. The top also comes in several colors. Judging by this pic, it also looks like a fair bit of work has gone into making the car look good with the top down. No word on what happens to trunk space, however.
