Rare Isdera Imperator 108i flexes its considerable muscles

The Isdera Imperator 108i is a remarkably rare supercar from the late 80s and early 90s. Born of a Mercedes-Benz concept car, it's powered by a range of AMG-developed V8s, with five to six liters of displacement, depending on the engine. The example shown here, lapping the legendary Spa-Francorchamps circuit, features the most potent 6.0-liter V8 available. And rather than just being driven about on a perfectly clean racing line, it's freaking power sliding!
Yes, there's something eternally childlike about a wedge-shaped supercar from our formative years being flung about a Belgian racetrack. Adding to the appeal is the Imperator's stumpy, periscopic rear mirror, sticking out of the roof. Even after being out of production for 20 years, this is still a wild, wild car and we'd happily snap up the opportunity pilot one of the 36 Isderas that were built. Take a look below for the full video from Spa.

Mercedes rules out hybrid supercar, promises SLS successor

The recent Geneva Motor Show was a festival of hypercars, with the presence of not one, but three over-the-top debuts: the Lamborghini Veneno, McLaren P1 and Ferrari LeFerrari. The latter two have hitched their carbon fiber bumpers to the electrification bandwagon by using hybrid-electric powertrains not entirely unlike the propulsion systems we've come to know in cars like the Toyota Prius and Chevrolet Volt. Does that mean the flow of electrons up the four-wheeled food chain will eventually consume our hallowed supercars? Not if AMG has anything to say about it.
AMG Director of Vehicle Development Tobias Moers recently confirmed that not only will there be a successor to the Mercedes-Benz performance division's SLS AMG, he notes that its internal combustion engine will most definitely not be sharing living quarters with an electric drivetrain. Instead, AMG plans to focus on further pushing the power and efficiency envelope of the internal combustion engine and advancing the use of lightweight materials to achieve their goals. The first example of this effort can be seen in the new SLS AMG Black Series that incorporates many weight-saving techniques to shed some 154 pounds from the SLS AMG GT (above), which itself is lighter than the standard SLS AMG.
Furthermore, Moers remarks that his company is happy to leave the hypercar segment to companies like Ferrari and McLaren. He admits that, "Ferrari in the hyper-car segment is still a different brand than AMG. We have to be honest..." So rather than taking the SLS further upmarket to do battle with bulls and stallions, Moers hinted that the next-generation SLS may be joined by another performance model that fits neatly between itself and the C63 AMG.

Vision Mercedes-Maybach 6 Cabriolet is last year's concept with a soft top

Last year, Mercedes brought an absurd, excessive two-seat coupe to Pebble Beach called the Vision Mercedes-Maybach 6. We say absurd and excessive because it was a roughly 19-foot long coupe for just two people. It also packed a 750-horsepower electric powertrain. This year, Mercedes brought pretty much the same car, but now with a soft top and the suffix "Cabriolet." Because the Vision Mercedes-Maybach 6 Cabriolet is basically the same car as the coupe, it's also dripping with unashamed excess. It's still 19 feet long, it still carries only two people, and it still has 750 horsepower from electric motors. Mercedes claims that power will propel the car to 60 mph in under 4 seconds. Also like the coupe, it has a range of 200 miles on a charge, and with the right charger, can supposedly regain about 60 miles in 5 minutes. There are changes to the car, though. For one, it's painted a different color. Instead of the vibrant red of the coupe, the roadster is a navy blue that Mercedes says helps evoke the feeling of a yacht — more so than the size already did. It also has new wheels with a more conventional multi-spoke look. They're also have rose gold-painted accents. The change to a convertible body style alters the appearance of the Mercedes-Maybach 6 more than you'd expect, too. Now that a significant portion of the vehicle is finished in a contrasting color, the car looks a bit shorter, in a good way. It doesn't look cumbersome. The lack of a fastback also helps keep the tail from looking like it's sagging, as it does on the coupe. The interior of the Vision Mercedes-Maybach 6 Cabriolet is mostly the same as the coupe, too. It features the same white leather seats that blend into the doors and dashboard. It also has the wild wraparound display and clear center tunnel with light tubes that show the flow of electricity to the motors. Metal highlights are finished in rose gold hue, as is the stitching. The differences include more prominent shapes that imply air vents, as well as a wood floor with aluminum strips to complete the yacht feeling. Also, the buttons that dot the seats have Mercedes logos on them, and they're backlit. We also get a peak under the hood of the Mercedes-Maybach 6 Cabriolet. It opens up like pre-war cars with two panels connected by a center hinge. Because it uses compact electric motors and underfloor batteries, there's storage space under the hood.
