The concept

The Apendix is a four-wheel drive crossover equipped with 4+2 seats and four doors. It drives like any car, but has the capacity to stretch and reveal a third row of seats. The Apendix has a futuristic design, and its rear doors open up like the gullwing doors on the Mercedes SLS AMG.

The background

Have you ever wished you could stretch your car to fit an extra few friends or more cargo in it? The Apendix was created to combine two types of car categories into one: compact and SUV. I imagined this type of layout because in North America, most people drive to work alone, but need an extra 2-4 seats in the evening or on weekends (whether it’s for family or friends). Driving a minivan all the time as a solution is not very cool, but what if our cars could extend at the touch of a button?

How it works

To extend the Apendix, the driver stops the vehicle and activates the ‘Extended’ mode. The car then unlocks the rear frame and an electric motor extends the vehicle by three feet (one meter). A fold-flat third-row seat hidden in the floor can then be unfolded (similar to the ‘Stow ‘n Go‘ feature on a Dodge Grand Caravan). In ‘Extended’ mode, the rear ‘gullwing’ door opens up, to access the rear seats.

Will this car be heavier than a standard seat car? Probably, but not by much. Will it have better handling? Maybe, the longer wheelbase might help overall, and the steering and suspension will be built to adapt to both wheelbases.

What it’s used for

If you have kids, you probably don’t have a choice but to own an intermediate-size car or a minivan.  With the Apendix, you could have the best of both worlds and use your vehicle to commute and go out with your wife or girlfriend, but you would also be able to take the kids on a road trip without being cramped in a smaller car. It will definitely be much cooler to drive and easier to park than a minivan in any configuration, and it will also hold much more luggage and passengers when it is switched to ‘Extended’ mode. Of course this is still a concept, and it needs some engineering and design refinements, but it could evolve into a new product line.

The Designer

I hope you like this concept, I was impressed and satisfied with how the design came out. It was executed by Clarck McCune, who’s based in Tulsa, Oklahoma.
