Lexus Brings Fastest Car to CD's 2016 Lightning Lap

How did Lexus put up the best time this year? - It totally cheated - in a good way.

Car and Driver’s Lightning Lap is a fantastic 10-year record of what cars are really fast in their given sales class. It uncovers cars that are actually fast, like the Ford Focus RC, and which cars are dog-slow for the money on a racetrack, like the Tesla Model S. The testing is always done on the same track, so the cars earn their spots in a controlled environment. The Lightning Lap rules state that the “winners” are to be street-legal cars on street-legal tires. Lexus didn’t send a street legal car, nor did it put street-legal tires on it. Instead, Lexus sent its mighty RC F GT Concept Coupe shod with Yokohama racing slicks that CD said were loud enough “…to make your ears bleed.”

The Lexus RC F is a production performance coupe that has rear drive, a V8 and a lot of go-fast bits balanced with the sort of things that make a ride home from work tolerable. The production car ran a 3:05.8 time in 2015, which is not very impressive for its class. A Dodge Charger SRT Hellcat ran the course about two seconds quicker as a point of comparison. However, the track-ready RC F GT Concept put up a time of 2:43.2. How fast is that? Consider that the track-ready Lexus is faster than the 2016 Dodge Viper ACR, which “won” the contest this year by a full second. In fact, the only car ever tested by Car and Driver that was as quick, was the 2015 Porsche 918 Spyder, which put up a time just one tenth of a second faster than the Lexus.

So, aside from the racing slicks, what advantage did the Lexus RC F GT have? For one it has a modified engine. Instead of the 467 hp from its V8 the street version produces, CD estimated that the GT Concept version has about 500 hp. Furthermore, the Lexus RC F GT Concept had most of its interior trim stripped out (and a roll cage added back). Interestingly, the Lexus seems to have retained its 8-speed “direct –shift” automatic transmission, which CD said slowed the car down. Apparently, slow is relative, since the RC F GT Concept was faster than every the car in the history of the test. All but that million dollar Porsche.
