Marcos Ross Ambrose (born 1 September 1976)[1] is an Australian former racing driver and current Garry Rogers Motorsport competition director.

Ambrose stunned the Supercars Championship world when he qualified on pole on debut, at the Australian Grand Prix support race.

With a new Falcon BA, Ambrose gave the Ford team a great start to the 2003 season with victory in the first race of the Clipsal 500.

In the end he collected his second championship in the opening Saturday night race and then went on to clean-sweep the round in record-breaking style in his Pirtek Falcon.

I knew that I was already 99% past him, I gave him a car-length and a half to go two-wide up into The Cutting, and I just got clean wiped out.This crash, combined with a poor performance on the Surfers Paradise Street Circuit arguably lost him a third straight title.

He thereafter supported teammate Russell Ingall's title bid successfully, and the two helped Ford and Stone Brothers Racing take the Drivers, Teams, and Manufacturer's championships.

In March 2015, Ambrose took a temporary leave from DJR Team Penske in order to improve his practice with V8 Supercar racing, being replaced with Scott Pye.

[9] He returned for the three-round Pirtek Endurance Cup as Pye's second driver, claiming an eighth finish at Surfers Paradise race 1.

In the interview, Ambrose said that the ultimate reason was that, "My time was up," and that he was "Putting the team first" in making his decision to step aside from the car after only two races.

Ambrose made his Truck Series debut on 1 April 2006 at the Kroger 250 at Martinsville Speedway, qualifying 20th and finishing 33rd after being caught up in an incident unfolding in front of him.

This was the first time a non-American driver has finished in the top five of a truck series event since Canadian Ron Fellows won on the Watkins Glen road course on 26 June 1999.

The next week, he made further history by scoring his first pole position for the Built Ford Tough 225 at Kentucky Speedway,[15] and then leading the most laps in the race itself, though he finished 19th.

At the 2007 NAPA Auto Parts 200 Nationwide Series race at Circuit Gilles Villeneuve in Montreal, Ambrose was the dominant driver of the day, having led for 37 laps.

After a caution period had finished, Ambrose had well-known Sprint Cup regular and Dakar Rally racer Robby Gordon behind him.

Ambrose admitted "getting into the back" of road course specialist, Said, causing Said to wreck and ruining his chances at a race where Said has consistently finished in the top 10.

He almost won the 2008 NAPA Auto Parts 200, dominating again like in 2007 but when a thunderstorm blew the track, Ambrose tried to slow for a pit stop.

Nonetheless, his car slid across pit road too fast unable to stop because of the waters; thus he earned a black-flag for a pass-through penalty.

However, a bad finish at Homestead put the team back out of the Top 35, so Ambrose would have been required to qualify on time for the first five races of 2009.

As a result, Ambrose attempted to return to his spot, but was forced to fall to seventh on the restart due to not maintaining a particular speed during the caution,[27] and finished sixth.

"[28] Ambrose announced on 17 August 2010 that he signed a multi-year deal with Richard Petty Motorsports to drive the #9 Stanley/DeWalt Power Tools Ford Fusion.

Sour Cream Dips at The Glen on 15 August to rack up his first career Sprint Cup Series win by passing Brad Keselowski and Kyle Busch with two laps to go.

Ambrose further vindicated his road course abilities, backing up under a week later by taking an emotional victory at Montreal in the Nationwide Series, during the NAPA Auto Parts 200.

In February he almost won the Budweiser Shootout with bump-drafting help from Keselowski; but lost the lead just as he took the white flag to Tony Stewart and eventual race winner Kyle Busch.

The following week, Ambrose won the pole at Infineon Raceway but only led about 10 laps before he had to pit thus putting him in the top ten for the rest of the day.

[29] Returning to Watkins Glen, Ambrose started fifth and dominated part of the race but was passed in a three-wide move by Kyle Busch with 20 laps remaining.

This fight for tenth place resembled a reverse style of Ambrose's race at Montreal in 2009, which ended with Edwards getting by him on the final lap.

With 3 laps left while running in 8th place Ambrose tangled with road-course rival Max Papis, ending his hopes to win three races in a row at the Glen.

Had he won, Ambrose would have joined Jeff Gordon and Mark Martin as the only drivers in NASCAR history to win three consecutive races at the Glen.

I've enjoyed my time here and I will miss my friends and the other drivers very much but this move is done mostly to help my children get raised in our native country and I feel like I want to start a new chapter in my life.
