If you've ever been curious about how quickly the DeLorean DMC-12 time machine from Back to the Future could reach 88 mph, today is your fortunate day. AirShaper has launched a 3D model of the iconic movie car that you can manipulate and explore. Alternatively, you can check out the company's report to discover its aerodynamic efficiency.
AirShaper is a cloud-based computational fluid dynamics (CFD) design tool. CFD software uses mathematical models to simulate the flow of liquids and gases over surfaces, providing insights into the aerodynamic characteristics of a car (or other vehicles) without the extensive time and costs associated with physical wind tunnel testing. We've previously featured content from AirShaper—a professional NASCAR engineer utilized their aero analysis tool for Lightning McQueen earlier this year.

The analysis reveals a drag coefficient of 0.10, indicating a high level of efficiency. For comparison, the aerodynamically optimized Lucid Air has a drag coefficient of 0.19, which doesn't include the various movie-prop paraphernalia at the rear. The time-travel mechanism is one of the primary contributors to drag, illustrated by a cloud of low-pressure air trailing behind the car, resembling an opened parachute. The flat hood also creates a similar airflow disturbance, while the blunt front end disrupts the airflow effectively.
Nevertheless, a low drag coefficient means the engine doesn't have to exert excessive effort to propel the DeLorean to time-travel velocities. This is advantageous, given that the DMC-12's Peugeot-Renault-Volvo 2.8-liter V6 engine produces only 130 horsepower. This limitation has inspired various inventive powertrain swaps, including Chevrolet V8s, electric drives, and even a 630-hp twin-turbo V6 from a Kia Stinger.
