One Lap of the Web: Stop! It's Sledgehammer time!

-- There's a Bitter SC on eBay this week, and unlike most examples that we see on the list that is Craig's and the Electronic Bays, this is actually in decent shape. Some of you might remember these when they were new, and they remain the best way and perhaps the only way to get into an Opel Senator on this side of the Atlantic.

Mercedes SLS AMG E-Cell (2010): the electric SLS

Following the unveiling of Tesla's updated Roadster 2.5, Mercedes is showing off its iteration of an all-electric sports car: the SLS AMG E-Cell. While the regular SLS pumps out 563bhp and 479lb ft from its 6.2-litre V8, the SLS E-Cell has four synchronous electric motors, powering all four wheels for a combined output of 392kW (equivalent to 526bhp) and a mammoth 649lb ft of torque. Crucially, all of that power is accessible from zero revs, allowing the E-Cell to sprint to 62mph in four seconds dead.
