The '90s were a wild time. The rise of the internet and shifts in pop culture led to some rather strange trends, many of which are remembered as downright weird. For cars as well, the '90s were a time of change and strangeness, (mostly) growing out of the angular '80s style with smooth curves that led to some rather interesting designs, some of which have aged horribly and some which still hold up as great, modern-looking vehicles to this day.

The insanity didn't end with the exterior design either, as a car's interior is the most important for the actual owner, and can be just as defining of the overall car. Especially with sports cars, the '90s style reached perhaps its most extreme and insane when it came to interiors. From wildly curvy designs that embraced the '90s aesthetics, to holdovers from the '80s that were taken to new extremes, these are 10 of the most insane sports car interiors from the '90s.

10 TVR Cerbera

An insane interior from a brand whose entire image is of insane cars, the TVR Cerbera came about in the mid-'90s as the brand's more touring-oriented 4 seater sports car. Like the mythical Cerberus its name was derived from though, the Cerbera was still an absolute monster.

Offered with a rather ridiculous selection of color schemes, the Cerbera's interior is a wild design that looks more like an alien spaceship than any road-going vehicle. From its debut in 1996, the Cerbera's calling card was its unique in-house designed V8 with up to 420 hp, making the entire car a distinct, and rather insane experience.

9 TVR Chimaera

Another bit of TVR insanity, the Chimaera's interior, and mechanical aspects are rather "normal" compared to the Cerbera, but against any other car from its time, the Chimaera is still a ridiculously unique design, inside and out.

Using the more normal 275 hp Rover V8 that the brand had been using since the '80s, the Chimaera was, and still is TVR's best-selling model. First made in 1991, the Chimaera, like the Cerbera, was a more comfortable touring-oriented sports car. As part of that, the leather-wrapped interior is soft and sumptuous, but also uniquely sporty at the same time.

8 Aston Martin V8 Vantage V600

A shockingly powerful monster, the V8 Vantage V600 came about in the late '90s, and despite being rather obscure, was the most powerful car to wear the brand name for over a decade.

Starting off life as the V8 Vantage, in turn, a performance version of the Virage, the V600 spec was a comprehensive upgrade package from Aston Martin Works first offered in 1998, with a myriad of performance parts all around, and most importantly tuning to the engine that brought it up to 600 hp - a figure that wouldn't be topped until the 2009 One-77. One of the most insane British cars of the '90s, the interior is just as awesome, blending classic and luxurious British design with some supreme sportiness.

7 Dodge Viper

Sadly gone from Dodge's lineup, the Viper was introduced in the early '90s to great fanfare. A legend to this day, the Viper was mainly known for one thing in particular - being an absolutely insane monster that could scare even the most composed drivers.

While rather basic in equipment, the overall layout of the Viper's interior is like very few other cars. Essentially a plastic tub, elements like the ridiculously wide armrest, giant speakers between seats, and wall-like dashboard give the Viper's interior an unmistakable look and one that's absolutely vicious when considering the power it commands.

6 Toyota Supra

One of, if not the most legendary Japanese sports cars of the '90s, the 4th generation Supra gained massive fame over the years following its release, beloved for its insane tuning capabilities, good looks, and properly sporty interior.

Turning the more grand touring-oriented Supra nameplate into one of a performance beast, the Mk4 Supra was released in 1993 with the legendary 2JZ inline-6 engine. On the inside, this new Supra was as sporty as could be, with an extremely driver-focused design that involved a wrap-around dashboard that looks closer to a fighter jet's cockpit than a road-going car.

5 De Tomaso Pantera SI

Via Classic Driver

Born in the '70s, the De Tomaso Pantera was a legendary mix of American V8 muscle and exotic Italian sports car construction. Evolving over the years, the Pantera received a new design for 1990, staying on sale until '92 as the Pantera SI.

Still quite similar to the '70s and '80s Panteras, the SI still used an American V8, and had an interior that kept a close resemblance to the layout of those original Panteras, but with modern (for the '90s) touches. A wicked blend of classic '70s and '90s design elements inside and out, the Pantera SI was an insanely unique, and uniquely insane monster.

4 Ford GT90

Sadly never produced beyond a concept car, the Ford GT90 was a fully functioning prototype meant to both pay homage to the GT40, and introduce Ford's new design philosophy for the 21st century in the wildest way possible.

Via Concept Carz

Created with some incredibly intense technology for its time, the GT90 was, and still is among the most incredible concept cars ever made. Powered by a V12 made from two modified Lincoln V8 engines, with an array of 4 turbochargers to boot, the GT90 could do 0-60 mph in just 3 seconds, an incredible feat when it was introduced in 1995. Just as incredible though, is the interior. Mirroring the exterior design themes, the GT90's interior may just have been a concept but was downright insane and holds up as such to this day.

3 Renault Alpine GTA Turbo

One of the most underrated classic French sports cars, the Renault Alpine GTA was a genuine Porsche beater, imbued with some seriously funky style, and some great performance for its time.

While the lightweight, remarkable handling, and rear-mounted V6 with 197 hp made the GTA a great performance machine, its style is like few other cars out there. A blend of angular and curvy proportions, the interior is where the GTA really shines. Introduced in 1984, and sold until 1991, the GTA's interior is the perfect mix of the '80s and '90s style, done up in a uniquely cool French way.

2 Subaru XT

Not to be confused with the turbo-trim designation Subaru currently uses, the XT was An '80s sports car that briefly held out on sale through the '90s, and was the brand's strangest sports car, beating even the SVX in terms of quirky design. While not a real success, and not all that fast, the Subaru XT annihilates the competition when it comes to insane interiors.

Via Motor1

Attempting to break from their un-exciting image, Subaru designed the XT as an aerodynamic wedge sports car, introducing it for 1985, and keeping it on sale until 1991. Not all that sporty in reality, the XT' was more like an arcade machine than a car on the inside. With an all-digital dashboard that tilted as a unit, an L-shaped steering wheel, and an airplane-style joystick for a shifter, the XT's interior is still among the most unique designs of all time.

1 Lamborghini Diablo

Insane inside and out, the Lamborghini Diablo today may not get the attention its predecessor and successors receive, but back in the '90s was one of the wildest cars in existence.

First going on sale in 1990 as a product of Chrysler's purchase of the Lamborghini brand, the Diablo was a continuation of the V12 Lambo flagship range, building on the Countach's legacy. Sold with an initial interior that was already wild (pictured at top of entry), the Diablo's interior received a facelift for the end of the '90s that introduced the even wilder style pictured above.
