F1 1988 Review DVD
1988 saw McLaren-Honda rewrite the record books as they redefined performance - taking 15 wins out of 16 races between them - and this action-packed review retells the thrilling story from beginning to end.
The last year of turbo engines was suitably thrilling, albeit almost completely dominated by the McLaren team mates Ayrton Senna and Alain Prost. They may have been driving for the same team but the two biggest stars of the 1980s were, unsurprisingly, extremely motivated. Neither gave an inch to the other on track, leading to several clashes, and sowing the seeds for future rivalry.
What the drivers said, how the teams worked, who held the joker at Monza and how the teams travelled the World; all these fascinating questions are answered when Stirling Moss and Tony Jardine give you your pass to the pitlane.
F1 1989 Review DVD
Unlike 1988, the first year of the non-turbo era was anything but a walkover for McLaren-Honda.
With Senna and Prost remaining with the British team for 1989, McLaren had the two most talented drivers in the field on their roster and every reason to believe they were in with a good chance of another Driver’s and Constructor’s title double.
Then Ferrari wins came in Rio, Hungary and Portugal, Benetton-Ford in Japan, Williams-Renault in Canada and Adelaide.
In the end the biggest threat came from within, as the bitter rivalry between the two legends boiled over into spectacular scenes on and off the track culminating in a controversial clash at the penultimate race of the year: Suzuka.
F1 1990 Review DVD
The 1990 season was one of the closest in years as the lead swayed between Ayrton Senna and reigning World Champion Alain Prost - now driving for Ferrari.
Senna opened his account for McLaren Honda in a thrilling season opener at the street circuit Phoenix, Arizona. Wet qualifying threw the expected grid into disorder and put Senna in fifth place, the fight back to the lead set the scene for the season.
The cavalcade moved to Brazil where Prost drove a typically calculating race to take nine points. Monaco and Canada: advantage Senna.
All season the pendulum swung back and forth as each of the great teams found small advantages for their star drivers.
As the teams headed to the Far East with everything still to play for, the Japanese Grand Prix became the most important, and most controversial, of the season.
