Mercedes-Benz drops first sketches of S-Class Coupé concept

The first batch of official sketches of Mercedes-Benz's S-Class Coupé Concept emerged this morning ahead of its unveiling at next week's Frankfurt motor show. The S-Class Coupé Concept previews the production model that will replace the CL-Class Coupé, and the first glimpse provides us with views from every angle. From what we can see, it mixes elements of S-Class – dropping feature line, rounded rear screen – with a pinch of SLS – hood power domes, rear lamp graphics and cab-rearward proportions.

Lamborghini Aventador J at 2012 Geneva motor show

There maybe other Italian sports car manufacturers looking to hog the limelight at the 2012 Geneva motor show (and Ferrari and its 730bhp F12 is one of them) but Lamborghini will vie for attention with the Aventador J. A two-seat, open top speedster based on the Aventador LP700-4, it has some intriguing bits of carbonfibre tech and highly individual design. Named 'J' after the FIA’s Appendix J that governs the tech spec of race cars in certain classes, it’s proper bedroom wall material – but little boys and girls are unlikely to ever see it on the road as it’s a one-off and will go to a lucky owner after its appearance at Geneva.

Craigslist catch: 1986 Lotus Turbo Esprit

For the masochistic car enthusiast--and many of us here at AutoWeek count ourselves among that breed--nothing is sure to tantalize and frustrate quite as nicely as a Lotus. Not just any Lotus, mind you, but a peaky, force-fed, emissions-saddled 1986 Turbo Esprit. The example shown here, http://detroit.craigslist.org/okl/ctd/2318628863.html, appears to be a fine specimen of Giguaro's wedgy Brit, and the rear-quarter decals indicate that this is a late HCi model--high-compression plus Bosch fuel injection.
