I know what you guys mean about American car magazines, honestly Car & Driver has never been the most credible magazine when it comes to acceleration tests. If my memory serves me correctly they achieved 0-60 mph in 3.4 seconds and 0-100 in 7.4 seconds for the Corvette C6 Z06..
Which as you see is a little too fast, it's not the first either, back in 2003 Car & Driver claimed using a Mercedes-Benz SL600 they achieved 0-60 in 3.6 seconds, after the countless letters sent to the editor it was revealed the SL600 was using a Maybach engine... So...Perosnally, the only American magazine i like and trust is Road & Track. They offer tons of data which always seems to match up with European test data. Let's wait until Sport Auto or AMUS gets a hold of the E63 Touring and see how their numbers compare.
