...but ACBC - the brains behind the glories that were the 79, skirts, the 25, even the lovely JPS paintwork,etc, etc. Still to my mind, the most innovative race car designer - died over 30 years ago.
The current "Lotus" team is a licencing agreement, as far as I know. That started 20 years ago, when the company we know as producing Lotus cars wound up its F1 program.
This is not to say that the contemporary Lotus team's technology is not impressive, but the cars racing in 2015 have little to do with what Lotus was a doing in the 60s and 70s. (Not to mention that, regardless of team, the current F1 rules are an anathema to innovation)
