1966 Italian Grand Prix

Jack Brabham was odds-on favourite for the Championship – only John Surtees could stop him and only then by winning all three remaining races. He was prevented from doing so by an impressive performance from his former employers Ferrari at their home track. Honda had brought a new 370 bhp 3 litre V12 engine for Richie Ginther, whilst Dan Gurney had his Weslake engine and Graham Hill had the BRM H16. Lorenzo Bandini and Mike Parkes led from the start, whilst Hill's engine gave up on the first lap, followed in retirement by Jackie Stewart on lap 5 with a fuel leak, and then Brabham on lap 8 with an engine failure which coated the car in oil. Jim Clark in the H16 Lotus was moving strongly through the field. On lap 17, Richie Ginther had a horrific accident, crashing heavily into the trees and being very fortunate to escape with his life. Once Clark had pitted, Ludovico Scarfiotti, Parkes, Surtees and Hill disputed the lead until Surtees withdrew with a split petrol tank which was pouring it all over his tyres and ending his championship chances. Denny Hulme had fought through the field to third place. But the race was Scarfiotti's, as he became the first Italian to win for Ferrari at Monza since Alberto Ascari in 1952. Parkes completed Ferrari's joy as he pipped Hulme by 0.3 seconds to claim second spot. Amidst all the celebrations, Jack Brabham was crowned champion. Apart from three NART entries in 1969 this race was the last time a Ferrari car was entered by a privateer team when Giancarlo Baghetti drove a private car entered by the British Reg Parnell team.

• Clark, Geki, and Spence switched numbers for the race when they are driving the same cars.
• Phil Hill's car was driven by Gurney in practice, but he would drive car #30 of Eagle-Weslake for the race.

• Ludovico Scarfiotti was only the third Italian to win his home Grand Prix, after Nino Farina and Alberto Ascari.
• This was the Formula One World Championship debut for British engine supplier Weslake.

• Notes: Only the top five positions are included for both sets of standings. Only the best 5 results counted towards the Championship. Numbers without parentheses are Championship points; numbers in parentheses are total points scored.
