The old content is awesome and is never going to stop being relevant. I think the key to address the criticisms would be

1) Navigation - perhaps some sort of timeline that accompanies each article so that you can easily see the context that technology is in (e.g. direct injection <- fuel injection <- carburetor).

2) Edit the copy to ensure that old technology isn't identified as new. A quick glance turned up examples like: "Some high-performance engines do not have carburettors...".

Good stuff overall though!
