A blend of haute couture and engines is what gives concept cars their unique appearance. These cars either tend to fascinate car enthusiasts or make them skeptical about the future. Looking at the bizarre design of the car’s body, it is easy to suspect that the overwhelming style suppresses the performance.

It is true that many of these cars do carry some practical function but not all of them store the legitimate power that a functional car generally requires. Behind the outlandish and bold creative look, many of the concept cars hardly produce enough acceleration or speed to make it worthy of a drive on the road.

Very few concept cars ever actually end up hitting production, and they're mainly responsible for providing ideas and innovation. These cars while definitely looking the part, aren’t entirely functional as modern vehicles! Here are 15 sluggish concept cars we do not want to drive!

15 Ford Nucleon

Ford Nucleon was successful in gearing up applause for featuring a futuristic style with a streamlined body and pillarless windshields. Regardless of its creative achievement, the two-seater was powered by a jet engine that only produced 100 horsepower, reaching a measly top speed of 84mph! Not really the standard you’d expect from a jet engine.

Volkswagen features an all-electric concept car with the Volkswagen ID Buggy. It’s based on a Modular Electric Toolkit (MEB) and was popularly called a dune buggy due to the original vehicle serving as its inspiration. However, the car’s speed is limited to 25 mph while its top speed under electronic tech is up to 99 mph.

With soft rounded features and a cute small body, the Volkswagen Colani is instantly recognizable even without the cluster of holes representing the grille on the hood. It didn’t receive any compliments on the appearance and the 13-horsepower rated engine could only power the car to a top speed of 43mph!

12 2005 Fiat Oltre

The four-door SUV body of the Fiat Oltre incorporates the rugged nature of a jeep, but that concept remains bound to the body’s exterior. The engine enclosed underneath the body does not hold much mechanical power. Although it produces 182-horsepower it lags behind with a low top speed of 81 mph.

11 Lexus LF-SA

Lexus LF-SA was revealed first at the Geneva Motor Show with a “bold and emotional” theme according to TopSpeed. It is a smart combination of a hatchback and crossover with a sleek body but doesn’t carry significant power. With a top speed of approximately 130 mph, LF-SA covers 0-60mph in a slow 12.5 seconds.

10 Chevrolet EN-V 2.0

Chevrolet’s EN-V had pure intentions of being a counter to the increasing levels of environmental degradation in the world. However, the design was a dud. The two-seat urban car aims to combat the environmental problems using a 3kW electric motor that can only drive at a top speed of 25 mph.

The egg-shaped body of the Citroen C10 surely caught the eye! Yet, the strange concept doesn’t deliver adequate speeds and powertrain. Underneath its steeply curved frame lies a small 425 cc engine that produces an extremely low top speed of 68 mph and takes a sluggish 21.2 seconds to reach the 0-60mph mark.

8 1950 Martin Stationette

The 1950 Martin Stationette was inventor, James V. Martin’s last work. The car’s construction did not cost any hefty sums as the entire body along with the chassis is built out of wood. The car never went into mass production and remained a prototype. It made a top speed of only 60mph.

7 2014 Honda FCV Concept

greencarreports.com

In 2014 the Japanese motor company followed its FCX concept and created another fuel-cell-powered concept car known as the Honda FCV. The innovation in technology is hands down remarkable but it does not hold any significant power. At a modest 134 horsepower, the car goes from 0 to 60 in a long 10 seconds.

6 2001 BMW X-Coupe

car-revs-daily.com

With the 2001 X-Coupe, BMW doesn’t fall at a great distance from the non-functional eccentric concept appearance. The concept car is based on the X5 off-roader’s chassis. But most of the mechanical power output employs an average powertrain which boasts a 184-horsepower. The average powertrain leads to distinctly average performance numbers!

5 Volkswagen Atlas Tanoak

Generally, the average time span a car should take to accelerate from 0 to 60 is 8 seconds. Cars exceeding the time imply that their acceleration is lacking the necessary oomph! Volkswagen’s concept car, the Atlas Tanoak takes almost 8.5 seconds to reach 60 mph. The pick-up truck inspired concept doesn’t qualify as a hotshot.

4 Mercedes-Benz Bionic Car

Another unique concept car that shows off a futuristic car with a retracted hood, the Mercedes- Benz Bionic was intended to capture fish body look. However, in the attempt, the car failed to include a useful power output. Using only a 1.9L engine rated at 138-horsepower the car reached 60mph in 8.2 seconds.

3 Smart Vision EQ ForTwo

Smart ForTwo is known for its eco-friendliness and leaps into the future with urban concepts and electric dynamics fitted in the car. The 2020 Smart Vision EQ walks in the footsteps of its predecessors and uses a 17.6-kWh lithium-ion battery that can only charge 80-horsepower and drags the car to 60mph in 11.6 seconds.

2 Pontiac Aztek

Pontiac’s Aztek is known as the ugliest car ever made and the audience holds nothing back when expressing their distaste for the car’s unlikable exterior. However, it’s not just criticized for the way it looks. The performance of the vehicle is absolutely dreadful. Pontiac was held in high regard for making fun cars before the embarrassing Aztek!

1 1985 Cadillac Cimarron

The 1980s is an era of classics, vintage coupes, and fierce race cars. A concept car like the 1985 Cadillac Cimarron bears the era’s tone but lacks the power that was all the rage back then. The concept car uses a 2.8L V-6 driving the car from 0-60 mph in 10.6 seconds.
