If you’ve ever been curious about how easily the DeLorean DMC-12 time machine from Back to the Future can reach 88 mph, today is your day. AirShaper has unveiled a 3D model of the iconic vehicle that you can interact with and examine personally. Alternatively, you can check out the company’s report to find out how aerodynamically efficient it truly is.
AirShaper is a cloud-enabled CFD design application. CFD stands for computational fluid dynamics, and it models the behavior of liquids and gases over surfaces mathematically. This gives insight into the aerodynamic characteristics of a car (or other vehicle) without the significant time and financial investment of conducting tests in a physical wind tunnel. We have previously featured contributions from AirShaper—a professional NASCAR engineer presented their aero analysis of Lightning McQueen earlier this year using this tool.
The analysis indicates a drag coefficient of 0.10, which is quite efficient. The aerodynamically optimized Lucid Air has a drag coefficient of 0.19, and that’s without the additional movie-prop clutter on the back. The time-travel components are one of the primary contributors to drag, depicted by a cloud of low-pressure air swirling behind the car akin to a deployed parachute. The flat hood also creates one of these clouds, while the rounded front end effectively obstructs airflow.
Nevertheless, a low drag coefficient signifies that the engine doesn’t need to exert excessive effort to propel the DeLorean to time-travel speeds. This is beneficial, considering the DMC-12’s Peugeot-Renault-Volvo 2.8-liter V6 engine only produced 130 horsepower. This has led to numerous inventive powertrain swaps, ranging from Chevrolet V8 engines and electric drivetrains to a 630-hp twin-turbo V6 from a Kia Stinger.
Interested in learning more about aerodynamics? AirShaper has a collection of sample CFD simulations that allow for comparisons between different vehicles, including aircraft and submarines. We maintain an active communication line with the company, so it’s likely you’ll see more of their intriguing models featured here in the future.
