The Sport doesn’t have the same level of personalisation available as the Pioneer Edition but still comes with flying lessons, while options include power heating and carbonfibre detailing.

This isn't the first flying car attempt in recent years...

The Liberty has a three-wheel layout and fold-away rotor blades on the roof. It's effectively a gyrocopter aircraft with two engines. Its Rotax engine-based dual propulsion drivetrain includes one engine for driving and one for flying. An unpowered large rotor on top creates lift, while an engine-powered blade at the rear provides thrust.

The PAL-V has low suspension and a tilting two-person cockpit.

To convert the car from driving mode to flying mode or vice versa takes around 5-10 minutes, according to PAL-V. The rotor mast unfolds automatically, but the driver must pull out the tail section, unfold the two rotor blades and take out the propeller to ready it to fly.

You also need a flying license, of course, and you can’t just take off and land anywhere; PAL-V says the Liberty requires take-off space of around 90-200x200 metres without obstacles. It says that small airstrips, aerodomes, glider sites and ultralight airfields will be most appropriate.

PAL-V says the noise that the Liberty generates in flight will be comparable to a small fixed wing aeroplane – “much less” than a helicopter.

The Liberty's drive mode engine has 99bhp and a top speed of 100mph, with 0-62mph sprint taking 9.0sec. Fuel economy is a claimed 31mpg with a range of 817 miles.

In the air, the flying car can climb to a maximum altitude of 3500m, and its 197bhp flying engine can propel it up to a top speed of 112mph. Its range is a claimed 310 miles.

The Liberty will be assembled in the Netherlands, with specific parts and systems manufactured by other companies in different countries.
