The Hennessey-prepped Jeep Grand Cherokee SRT600 is once again in the center of attention of the Bulgarian design firm Vilner. Back in October 2010, the company had launched its first take on the Hennessey Grand Cherokee SRT600 that packs a modified V8 engine fitted with a "Vortech" turbo system for an output of 600-horses.

For its second go on the Jeep, Vilner completely revamped the interior with red and black Alcantara combined with black leather trimmed in red seams. The company says it also designed a new flat-bottom steering wheel with its shape customized to fit the owner's personal preferences.

The Fiat Group is getting ready to take its alliance with Chrysler to the next level with the presentation of three new models including an SUV and two luxury sports sedans, all using key technology and components from the Chrysler Group's lineup, according to a report from Autonews.

First up is the long-rumored Maserati SUV model, which is said to be previewed by a concept study (not to be confused with the independent design rendering by Andrey Trofimchuk that is pictured in this article) at the upcoming 2011 Frankfurt Motor Show in September, before landing in showrooms in 2013.

The Chrysler Group’s newly formed Street and Racing Technology (SRT) brand has released pricing on its latest crop of models, which include the 2012 Chrysler 300 SRT8, the 2012 Dodge Charger SRT8, the 2012 Dodge Challenger SRT8 392 and the 2012 Jeep Grand Cherokee SRT8.

Prices together with an $825 destination fee start at $47,995 for the Chrysler 300 SRT8, $46,660 for the Dodge Charger SRT8, $44,077 for the Challenger SRT8 and $55,295 for the Jeep Grand Cherokee SRT8.

All four SRT8 models are powered by the Chrysler Group’s new 6.4-liter HEMI V8 with Fuel Saver Technology that cranks out 470 horsepower (351kW) and 470 lb-ft (637Nm) of peak torque (465 lb.-ft. / 630 Nm in the Grand Cherokee SRT8).
