Normally we’d be sad by the passing of an engine like AMG’s supercharged 5.5-liter V8, the über-huffer that’s powered many of our favorite Mercedes-Benzes. However, now that we’ve seen its formidable successor, AMG’s new naturally aspirated 6.2-liter V8, we’ve cancelled the wake and are planning a party instead. The new 2007 E63 sedan is the most powerful E-Class yet to blast out of Stuttgart, and it’s a delight to drive, especially when the 507 horses are fully unleashed.
