The 2+2 coupe is a long-standing tradition in motoring. The Porsche 928, Lamborghini Espada and Ferrari 330 GTC all adhered to this formula with impressive results.

UK designer Julliana Cho’s Porsche 929 concept study builds on this tradition while also weaving aerodynamic styling, the brand’s design heritage and an innovating car sharing program into the mix.

The 929’s theoretical dimensions make it smaller than the Porsche Panamera but larger than the 911. Aside from the design itself, what makes the 929 stands out from the pack is Cho’s imaginative (though possibly impractical and expensive) car sharing scheme.

It’s been a while since Porsche had a front-engined GT in its range. Most car enthusiasts will remember the 928 that was launched in 1979 with the aim to replace the 911 by offering improved drivability and increased passenger and luggage space.

Even though it was named “Car of the Year” in 1978, and was continuously evolved until production ended in 1995, it failed in its original mission since the 911, despite its shortcomings, far outlived it.
