their own collections if they so desired. The 1990s At the start of the 1990s, McLaren continued to dominate the sport with Ayrton Senna taking back-to-back titles in 1990 and 1991. McLaren signed the promising newcomer Mika Häkkinen as a test driver at the end of 1992, but by 1992 Williams was once more in the ascendancy. McLaren was not to win another title for seven years. With the loss of Honda power in 1993, Dennis was left haggling with Ford and Ford's works team Benetton for a supply of competitive engines. A disappointing partnership with Peugeot in 1994 failed to yield the expected results and left Dennis searching to find a fourth engine partner in as many years. In October 1994 he agreed terms with Mercedes-Benz to supply engines from 1995 onwards, an association that continued until 2014. The first couple of seasons the McLaren-Mercedes relationship was difficult, teething troubles with the engine, chassis challenges, and the driver for 1995 was the ageing Nigel Mansell who did not even fit into the car so Mark Blundell deputised. When a revised chassis was produced Mansell's performances were not successful. Mika Häkkinen gradually assumed leadership of the team but suffered severe head injuries in a crash at the end of the 1995 season, from which he eventually made a complete recovery. By the mid-1990s Dennis was once more guiding his team towards domination of the sport, and in 1996 he approached Williams's star designer Adrian Newey to become technical director of McLaren. Newey agreed, and in 1998 McLaren took both the drivers' and the constructors' titles with Mika Häkkinen. A second drivers' title followed in 1999, but Ferrari took the constructors' title. The 2000s In 2000 Dennis was made a Commander of the Most Excellent Order of the British Empire. In 2001 Jaguar boss Bobby Rahal attempted to lure Newey from McLaren. Details of how Dennis convinced Newey to stay have remained vague but rumours in the specialist motor racing press suggested a deal allowing the designer to work on racing yachts. In the same year, team leader Mika Häkkinen announced that he was to leave the sport. As a result, Dennis signed Kimi Räikkönen. In 2005 McLaren remained at the top of the sport following a poor year in 2004. Despite producing their strongest performance for several years and winning more grands prix than any of their rivals, McLaren were
