1980 CART PPG Indy Car World Series
The 1980 CART PPG Indy Car World Series season was the second in the CART era of U.S. open-wheel racing. It consisted of twelve races, beginning in Ontario, California on April 13 and concluding in Avondale, Arizona on November 8. The PPG Indy Car World Series Drivers' Champion and Indianapolis 500 winner was Johnny Rutherford. Rookie of the Year was Dennis Firestone. The entire season, including the 64th Indianapolis 500, was to be co-sanctioned by both the USAC and CART under the banner of the Championship Racing League (CRL). However, USAC withdrew from the arrangement after five races. The season-opening race at Phoenix, set for March 2, was cancelled due to local flooding and washed out roads. Johnny Rutherford in Jim Hall's Chaparral 2K ground effects chassis dominated the season. Rutherford won five races, including a dominating performance at the 1980 Indianapolis 500. Rutherford finished in the top five in the first ten races, pulling out to a commanding and unmatchable points lead. Rutherford started the season out by finishing 1st or 2nd in the first six races, and ended with a total of eight finished of 1st or 2nd. Rutherford's season was not without incident, however. In the final race of the season at Phoenix, while battling Tom Sneva for the lead, Rutherford tangled with a lapped car, hit the wall, then flipped over. The car landed upside-down hard on its rollbar, but Rutherford was not seriously injured. Drivers and constructors

Race summaries 
Race 1: Datsun Twin 200

For the opening race of the year, Johnny Rutherford qualified on the pole, with Bobby Unser, Al Unser, Rick Mears, and Tom Sneva making up the rest of the top five starters. Johnny Rutherford led the first eight laps, before Bobby Unser caught and passed in lap traffic. However, while leading on lap 14, he suffered a cracked radiator and dropped out. This moved Rutherford back in front, and he was mostly uncontested for the remainder of the race as most challengers had problems. Rick Mears dropped out due to electrical issues while running second. Pancho Carter moved up to second, but he dropped out with fuel pump problems, followed by Al Unser dropping out on lap 45 with a broken transmission. With most of his competition out, Rutherford cruised to an easy victory over Tom Sneva. Gordon Johncock finished third, Spike Gehlhausen fourth, and Tom Bagley fifth. Race 2: Indianapolis 500

This moved his brother Bobby Unser into second, and on the restart he managed to catch and pass Johncock for the lead, holding on to win.

Foyt took the lead on the first lap, and led most of the first half of the race, giving up the lead only for pit shuffling. The first caution came on lap 11, when Al Loquasto lost a wheel and Dennis Firestone wrecked in the same part of the track. The second caution came on lap 26, after Howdy Holmes lost control, Jim McElreath slowed and Roger Rager hit the rear of his car. While leading on lap 82, Foyt encountered a bad valve, and dropped out. This gave the lead to Bobby Unser, who led most of the rest of the race. Johnny Rutherford led 1 lap due to pit stop shuffling, followed by 5 laps under caution after Pancho Carter spun, but when the green flag flew after a caution on lap 165, Unser pulled away. Rutherford's hopes of winning ended with 20 laps to go when his engine stalled in the pits, allowing Unser to win the race by a wide margin over Rutherford. Tom Sneva finished third, Bill Alsup fourth, and Vern Schuppan fifth. Most other stars were taken out due to attrition. Al Unser was never a factor and dropped out with handling problems on lap 35.

Race 5: Red Roof Inns 250

Al Unser qualified on the pole, followed by brother Bobby Unser in second, Rick Mears in third, Johnny Rutherford in fourth, and Danny Ongais rounding out the top five starters. The start of the race was problematic. Starter Duane Sweeney didn't give the green flag when the pace car pulled off as the back rows were strung out, but the field got going anyway, with Al Unser spinning off track in the first turn. Two laps later they got back in two-by-two order for the official start. Danny Ongais and Sheldon Kinser didn't make it to the green flag, with Ongais having ignition problems and Kinser a blown engine. On the first lap, Tim Richmond spun off course and was hit by John Wood.

Rick Mears then took the lead, and throughout the next 20 laps dueled with Johnny Rutherford. After a poor pit stop by Rutherford, Mears had a 20 second lead, but due to heat exhaustion lost concentration and spun out while leading on lap 47. This gave the lead to Rutherford, with Mears's day ending on lap 54 after Rick Muther spun out and Mears hit him. This brought out the caution, allowing second place Gordon Johncock to close. But when the green flew, Rutherford pulled away and won, a rare road course win. Bill Alsup finished third, Roger Mears fourth, and Vern Schuppan fifth. Polesitter Al Unser lost a lap due to an unscheduled pit stop, and dropped out with suspension problems while running fifth. Rutherford now had a 770 point lead over Tom Sneva, who had crashed out.
