2019 McLaren Senna Top Speed Testing!
The Johnny Bohmer Proving Grounds (JBPG) runway, located in Merritt Island FL. is not only the widest and flattest runway in the world but also close to the longest. For over 10 years, Johnny Bohmer has been performing Straight Line Aerodynamic Testing for many manufacturers and thousands of vehicles here. The all concrete runway is 3 miles long with an additional 1000 ft. asphalt runoff on each end. The runway is also 100 yds. wide with an additional 50ft wide traffic lane on each side and has an elevation variance of only 1⁄4 in. from north to south over the 3 miles making this one of the flattest, large surface concrete platforms in the world. You hardly notice the 24 in. crown in the center of the runway due to the immense width of the surface. In todays’ time, the availability of concrete would make this runway impossible to build. The traction is also substantially better here than any street surface; not as good as a drag strip, but much better than the street.
Johnny Bohmer has developed a program to debunk myths and fact check the manufacturer’s claims of vehicles performance. While testing the vehicles, Johnny’s team will data log each vehicle and record the findings. These have been useful to many manufacturers because of the vehicles ability to drive at speed for 2.5 miles while still have a safe, shut down area. Performance videos will be posted to the public on the recently started, Johnny Bohmer Proving Grounds YouTube channel.
The vehicles being tested are timed and speed checked with Garmin and GoPro interior monitoring systems. External timing and speed are performed by the International Mile Racing Association (IMRA) who is a sanctioning body accepted by numerous auto groups and the Guinness Book of World Records. Johnny and his team will routinely test 1⁄2 mile, 1 mile, 1.5 mile, 2 mile, 2.3 mile, 2.5 mile and 2.7 mile distances. Manufacturers come from all over the world to test many types of vehicles at JBPG including sports cars, race cars, tractor trailers, electric vehicles, autonomous vehicles, fire safety, law enforcement and the list goes on.
On May 4, 2019, Johnny Bohmer had a small group of vehicles testing at JBPG; including the McLaren 720S, Chevrolet Camaro ZL1 1LE and Ferrari 599 GTB. The weather conditions that day are listed below.

Of the vehicles testing, one we were particularly interested in was a 2019 McLaren Senna. This is the first time that a true top speed test of a McLaren Senna has ever been performed.
The professional driver reached a speed of 204.100 MPH (328.467 KPH) during the 2.7 mile test!
One of the main functions of the Johnny Bohmer Proving Grounds is to safely determine all aspects of a vehicle’s performance capabilities while determining the accuracy of the manufacturer’s claims. Last but not least, please subscribe to the Johnny Bohmer Proving Grounds YouTube channel as we continue to perform more testing with some of your favorite vehicles.
