Gallery: History of hybrid cars in motorsport

Hybrid racing cars may have become commonplace only recently, but their presence in motorsport harks back to the late 1990s.

Exactly 20 years ago American high-performance car manufacturer Panoz made history when it debuted the Q9 GTR-1 Hybrid at the Le Mans 24 Hours. But perhaps the car was ahead of its time and it would take another 10 years before the next hybrid machine contested a race.

Nowadays hybrid technologies have become sophisticated to the point that they form the core of Formula 1 and FIA World Endurance Championship regulations.

F1 added KERS (Kinetic Energy Recovery System) as an optional feature in 2009, before making a switch to full-hybrids in '14. Endurance racing's hybrid era started two years earlier in 2012, when the new-formed WEC series made hybrids mandatory for all manufacturers in the top-tier LMP1 class.

In addition to F1 and WEC, hybrid racing cars can also be seen in the GT300 class of Super GT, Japan's premier sportscar championship.

Nicknamed Sparky, the Panoz Q9 Hybrid made a grand debut at the 1998 Le Mans 24 Hours race. Its makers had hoped that the additional electric power would lead to fewer pitstops, thus greatly increasing the chances of a strong finish. However, the batteries ended up having a negative effect, making the car too heavy and it couldn't even qualify for the race.

After making its first public appearance at the Geneva Motor Show, the Porsche 911 GT3 Hybrid was seen in action at the Nurburgring 24 Hours. Thanks to a flywheel-type hybrid system, the 911 GT3 Hybrid could complete 10 laps per stint as compared to 8 for its petrol-only rivals. Unfortunately, the car had to be retired two hours before the chequered flag.

Formula 1 adopted full-hybrid technology in 2014, with power generated both from regenerative braking (MGU-K) and the heat released from exhaust gases. There was a change in the Internal Combustion Unit (ICU) too, with 1.6-litre V6s replacing the old 2.4-litre V8s. Mercedes sweeped both drivers and constructors' title in the first year of hybrid era.

Hybrid cars weren't limited to just the GT300 class of Super GT. Honda raced the hybrid version of NSX Concept GT in the flagship GT500 category between 2014-15, but was forced to abandon it before the start of the '16 season as the negatives simply outweighed the positives.
