Porsche Panamera Mirage ConceptWith the Panamera, Porsche sought to combine the sleek aesthetics of a sports car with the roomy sensibilities of a sedan. In theory, the Panamera has been successful, having sold over 235,000 units in its first 10 years, well over Porsche's initial estimate of 200,000 cars.In practice, however, a four-door Porsche just looks ... off. Take, for instance, the Mirage, one of the concept cars that ultimately led to the Panamera's final design. It's bizarrely long, but still small, like a Dachshund, more commonly known as a wiener dog. The core problem, and something that will become a running theme in this list, is that if you try to combine a luxury sports car with another type of vehicle, then you lose what made it a sports car in the first place. This looks more like a station wagon on steroids than a proper sports car, and the lumbering hot dog looks like it would jarringly jut out of any reasonably sized parking space.2024 Porsche Taycan Turbo SPorsche's electric alternative to the Panamera is the Taycan. Pictured here is the 2024 Turbo S model, which also boasts a four-door design that just never looks right to our eyes. Still, we have to admit, if we absolutely had to get a four-door Porsche, it would probably be a Taycan. That being said, this vehicle suffers from the same issue as all the rest of Porsche's four-door lines, which is that the back half just feels unreasonably huge and unwieldy.Sports cars are supposed to be small and sleek, but the Taycan, despite its stylized lines and aerodynamic contours, is big and bulky. From a distance, it looks like a sports car, but up close, that appearance is a lie. The Porsche Taycan is like an overweight person trying to look thin by wearing black clothes with vertical stripes and sucking in their gut, but they're trying way too hard, which isn't precisely the look you want for a $200,000+ sport(y) car. Porsche Mission X PrototypeThe 2023 Mission X is a concept car showing the potential for the future of Porsche hypercars. Based on this vehicle, the future is Porsche trying to look like a Lamborghini knockoff. Seriously, this thing, while pretty in its own way, is visibly unrecognizable as a Porsche. It looks more like a UFO. The driver's seat is supposed to look like an airplane's cockpit, but with the glass dome-style roof, both driver and passenger can get sunburned like ants under a magnifying glass.Perhaps in a nod to aerodynamics, the Mission X doesn't have traditional side mirrors. In fact, it doesn't have any side mirrors at all. Instead, it has computer screens inside the car that simulate the visuals of a side mirror, called digital wing mirrors. Call us old-fashioned, but cars need mirrors. Real mirrors. They're an essential part of safe driving, and we don't want to trade them in for computer screens. Even if the computer screens are extremely low-latency, they'll never be as low-latency as actual mirrors!Porsche Cayenne Convertible ConceptRemember when we said there's nothing that can be done to make an SUV look cool? Well, Porsche tried, and the result was this monstrosity, a concept car that, thankfully, never made it to production. The concept, pun intended, is simple: Make a Cayenne into a convertible. However, the result is bulky, bizarre, and ugly. Family-sized cars are simply not meant to be convertibles. Come to think of it, maybe family-sized cars are not meant to be Porsches at all.If Porsche had been able to pull off such a ridiculous concept as a convertible SUV, they wouldn't have just stopped there. Had this thing gone to the assembly line, who knows what else Porsche would have done? Perhaps hockey rinks would be cleaned by Porsche Zambonis, we'd all be going to work in Porsche city buses, and our trash would be left outside to be picked up by Porsche garbage trucks! Thank goodness that future never came to pass, or this list would have a lot more than just 10 entries.Porsche 924Porsche's follow-up to the 914 didn't fare much better from an aesthetic standpoint. While the 914 was a humble offering that was overshadowed by its peers, it retains something of a timeless, if unassuming, profile. On the other hand, the Porsche 924 suffers from being the Porsche of the 1970s. After the expressionistic vehicles of the 1950s and 1960s, cars became a lot more utilitarian in the 1970s, aiming for efficiency over aesthetics, which were usually saved for extras like wood paneling (why was there so much wood paneling in the '70s?)The Porsche 924 looks like the entire decade rolled into one car, from the dopey headlights to the overall compact form factor. As a result, it looks terribly dated. Whereas the 914 looks vintage, the Porsche 924 simply looks old, an unfortunate side effect of catering to the trends of the time rather than carving out its own path.
