For 2007, Ambrose stepped up to the NASCAR Nationwide Series, driving the No.
59 Kingsford Ford Fusion fielded by Wood Brothers/JTG Racing.
In the first two races of the 2007 season, he finished on the lead lap, in 16th and 25th, on tracks he had never previously raced on.
In the third race of the season, the Telcel-Motorola México 200, Ambrose finished eighth, his career best at the time.
having gained several positions in the last few laps of the race.
He followed up his 8th-place finish in Mexico City with another top 10, finishing 10th in the Sam's Town 300 at Las Vegas.
He recorded a career best Nationwide Series finish of sixth after starting third at Dover in May.
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.
At turn 3, Gordon successfully made a pass on Ambrose and then the yellow flag came out.
At the next corner, Ambrose rammed the left-rear of Gordon's car, spinning him out under yellow.
Due to a caution being brought out earlier because of a large crash behind them, Gordon sped back behind Ambrose.
During the caution, NASCAR officials declared that Ambrose was actually leading at the moment of caution (even though video footage appeared to show otherwise) and that Gordon had not maintained cautious pace by stopping in the middle of the race-track after the spin.
Therefore, officials ordered Gordon to move back to 14th position for the oncoming restart, but he refused and was subsequently black-flagged.
When they restarted with 2 laps to go, Gordon intentionally ran into the back of Ambrose at turn 2, spinning him around.
Although the win slipped away, Ambrose dropped down the field but recovered to finish in 7th.
Following this incident, Gordon apologized and made a peace offering to Ambrose in the form of a ride for the Watkins Glen road race, in Gordon's No.
77 Camping World Ford Fusion.
However, qualifying was rained out and the field was set by owner's points, and the No.
77 did not make the race.

In September, Ambrose skipped a second opportunity to drive the No.
77 car because his wife Sonja gave birth to their daughter Adelaide on the same day as the Cup race at Dover.
Ambrose finished the 2007 season 8th in the points standings, highest of any driver not also competing in the Nextel Cup, and finished second behind David Ragan in the Rookie of the Year standings.
On Sunday 20 April 2008 Ambrose was involved in a racing incident with Boris Said in the Busch Series event in Mexico.
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.
After the race Said claimed that he was not mad at Ambrose, but wanted to apologize to (Ambrose's) crew chief, Gary Cogswell because it was going to "cost him a car," implying that Said will wreck Ambrose intentionally next time they find themselves on a NASCAR track together.
Even though NASCAR said that Boris just wrecked himself by getting loose, and that Ambrose has repeatedly apologized, in numerous subsequent public appearances, Said has not backed down in his threatening of Ambrose, at one point suggesting he would not apologize but preferred to "beat (Ambrose's) ass".

However, later that year at Watkins Glen when Ambrose was leading the NBNS race, in the final five laps he took the lead and with 2 laps left he raced behind the bumper of a lapped Boris Said.
Ambrose's crew chief Gary Cogswell ordered Ambrose to not pass Said believing that Said still had a grudge against them after Mexico City.
The fans, Ambrose, his team and among other NASCAR drivers were surprised when Boris Said did not commit his revenge before Ambrose later won the race.
To this day Said has not explained why he did not crash Ambrose when he had a good chance and it still remains unknown why Said did not perform his revenge.
