After [[Ford Motor Company|Ford]] acquired [[Cosworth]] in July 1998, they risked designing and building a brand-new engine for 1999. The [[Stewart SF3]] was quick out of the box, however both cars over-heated on the grid of the first race, the Australian Grand Prix, after qualifying competitively. This put Herbert out instantly and made Barrichello start from the pit lane. Barrichello received a stop-go penalty during the race and finished 5thfifth. The car was consistently competitive throughout the season, however the engine initially proved fragile as both cars blew their engines at the Brazilian race which meant the engine was rarely run at full power. Stewart's competitiveness was affirmed by running first in Brazil for a long spell of the race and qualifying on pole for the French Grand Prix with Barrichello. [[Johnny Herbert]] won a popular victory at the rain soaked [[1999 European Grand Prix]] at the new [[Nürburgring]] after other leading contenders crashed off the track or lost time in the pits changing tyres.<ref>''1999 European Grand Prix Race Report'' [http://www.sportinglife.com/formula1/reports/story_get.dor?STORY_NAME=others/99/09/26/manual_171313.html www.sportinglife.com] {{Webarchive|url=https://web.archive.org/web/20001121093100/http://www.sportinglife.com/formula1/reports/story_get.dor?STORY_NAME=others%2F99%2F09%2F26%2Fmanual_171313.html |date=21 November 2000 }} Retrieved 11 May 2006</ref> Barrichello finished third, in a result most observers indicated that Stewart deserved given their strength over the season. Johnny Herbert also became unwittingly influential in the championship at the next and penultimate race, the Malaysian Grand Prix. Running 3rdthird behind the [[Scuderia Ferrari|Ferrari]]s of [[Michael Schumacher]] and [[Eddie Irvine]], a mistake in the closing laps allowed [[Mika Häkkinen]] to slip past and claim the final podium position which gave the championship contender vital points. The Ferraris were disqualified for car irregularities and the win allowed Häkkinen to gain his second championship. The Stewarts as a result finished 2ndsecond and 3rdthird in the race. However Ferrari won an appeal and the initial result was reinstated. Häkkinen however went on to win the championship and Stewart came 4thfourth in the Constructors Championship beating teams such as [[WilliamsF1|Williams]] and [[Benetton Formula|Benetton]]. Stewart's last race was the [[1999 Japanese Grand Prix]].
After [[Ford Motor Company|Ford]] increased its commitment by buying the team out, it became known as [[Jaguar Racing]] for the 2000 season.<ref>{{cite web|title=Stewart Grand Prix|url=http://www.f1technical.net/f1db/teams/105|publisher=F1technical}}</ref> Poor results however, led to the team being sold for the 2005 season, becoming [[Red Bull Racing]].
