A handsomely-produced and superbly-researched history of the top racing series in the US, starting from its troubled birth in the late Seventies through to its status second only to Formula One in the late nineties. The narrative concentrates on personalities and themes rather than detailed event-by-event history and the technical side is downplayed a little, but it's very well-written and the production values (typically for any Autocourse title) are absolutely superb. The photography is, as usual, second to none.
This would get five stars, but I have to dock one one star for skimping on some of the most interesting stories -- for example, there's almost nothing about the Penske/Ilmor/Mercedes coup with the pushrod engine at Indy in '94. Still by far the best book I've seen on CART.
