Alex Gurney claimed Daytona 24 Hours pole position for the GAINSCO/Bob Stallings team as the Daytona Prototypes blocked out the first seven positions on the grid.
Gurney came out on top in the three-way, Chevrolet-powered battle for pole the inaugural United SportsCar Championship event with Spirit of Daytona driver Richard Westbrook and early pacesetter Christian Fittipaldi from the Action Express team.
Gurney finished on 1m38.217s aboard his Riley-Chevrolet Corvette DP, which was two tenths quicker than Westbrook's best in his Coyote 'Vette-lookalike.
Fittipaldi's Chevy-powered Coyote was initially in the hunt but was ultimately bumped to fourth by Brendon Hartley in the Starworks Motorsport Riley-Dinan/BMW.
The Kiwi ended up with 1m38.525s, which was just four hundredths slower than Westbrook.
Gurney, who also took pole at Daytona in 2007, said: "I'm really happy and pretty excited about this, because this is the biggest race of the year for me.
"All through testing we have concentrated on full-tank runs and when we took the fuel out, the time came."
Best of the rest behind the DPs in the Prototype class was the DeltaWing-Elan/Mazda DWC13, in which Katherine Legge ended up eighth - exactly one second from the pole.
P2 CARS STRUGGLE FOR PACE
The best P2 car was the Pickett Racing/Muscle Milk ORECA-Nissan 03 in 11th place with a time of 1m39.829s set by Lucas Luhr.
The Muscle Milk entry was the only P2 to end up ahead of the fastest contenders in the one-make Prototype Challenge class.
The Extreme Speed Motorsports HPD ARX-03b driven by Johannes van Overbeek was the second-fastest P2, albeit two seconds slower than Luhr.
Colin Braun was quickest in the PC division for the ORECA-Chevrolet FLM09. His best in the CORE-run entry of 1m41.777s just edged out Renger van der Zande for the top spot in class.
VIPER TOPS GT PACK
Marc Goossens claimed pole in the GT Le Mans class for Chrysler's SRT Viper squad with a time of 1m44.505s.
That put the Belgian less than a tenth of a second up on the factory CORE Autosport Porsche 911 RSR, which finished on a 1m44.582s.
The second Riley Technologies-run Viper GTS-R ended up third in the hands of Jonathan Bomarito, who was a further six hundredths in arrears.
A tenth back was the best of the new Chevrolet Corvette C7.Rs, which was fourth quickest with Oliver Gavin at the wheel.
Honours in the GT Daytona class went to the Paul Miller Racing Audi team and Christopher Haase. The German's time of 1m46.973s put him less than a tenth ahead of Toni Vilander's Scuderia Corsa Ferrari 458 Italia.
