TOP 5: WEIRDEST CARS EVER DESIGNED

1 Purves Dynasphere (1932)


          

Who said you had to have at least two wheels to ride in style?  Dr. John Purves, following designs, were originally drawn up by Leonardo da Vinci, invented the Dynasphere — a monowheel electric vehicle — in the early 1930s.
Dr. Purves took to the beaches of Weston-Super-Mare to demonstrate his contraption, which was capable of reaching speeds of 25mph. If that does not sound too impressive, bear in mind the Dynasphere’s inability to brake or steer to any great effect would have made it quite the challenge to pilot.
Accounts report that trying to break with anything other than the gentlest of pressure would result in a phenomenon known as “gerbilling”, where the rider would begin rotating within the wheel without the capacity to stop.

2 Waterman Arrowbile (1937)


          

Soon after the Wright Brothers seminal flight landed safely, inventors began thinking of ways to combine aircraft and automobiles.
One such man was Waldo Waterman, a designer who specialized in the early push to develop a “flivver” — an affordable aircraft. His was a car that could also take to the air.
In the end, Waterman only ever produced five Arrowbiles, meaning that this motoring oddity is as rare as it is unique.

3 Parallel Parking Car (1927)


         
A trip to the local high street can tell you that many drivers wouldn’t be able to call themselves experts at parking, and the most loathed maneuver — the parallel park can leave even the most self-assured motorists longing for a self-driving car.
In fact, when searching for a spot, drivers are happy to travel almost 100m further than necessary to find an easier place, if the first space looks a bit tight for a parallel park.
It may come as a surprise to many but a solution was invented 91 years ago. In 1927, the parallel parking car was first seen on Parisian streets. The car’s front wheels would turn 90 degrees, allowing the car to swing in or out of an empty space like a door on hinges, making parking in tight spots look easy.
The fact that it never took off suggests the system was flawed in other ways, perhaps lacking the robustness required for everyday driving, badly impacting on handling characteristics, or limiting options when it came front-end packaging and design.

4 Propeller Car (1955)


      

During the 1950s, Clifford Robbins, like many mechanically inclined young men of his time, decided to build his own car. What emerged from Robbins’ Somerset workshop in 1955 was a car like none before.
His Propeller Car dispensed with a traditional drivetrain; instead, thrust was provided by a large fan at the rear, much like a wheeled hovercraft. The contraption was a one-off and reportedly took Robbins six months to build.

5 Streamline Cars R-100 (1930)

          

Sir Charles Dennistoun Burney was many things during his distinguished life: a politician, a businessman, an inventor and an aeronautical engineer to name four. His work as the latter saw him come up with the ‘Paravane’ anti-mine device during world war one, before he moved on to Vickers, a defunct British engineering company, resulting in the R100 and R101 airships.
In the 1930s, he used his knowledge of aerodynamics to set up Streamline Cars Ltd, building high tech aerodynamically advanced rear-engined vehicles. That work inspired the creation of the ovoid R-100 car which was only reproduced 12 times. The Prince of Wales bought one of the streamliners in 1930. Only two of the cars are believed to survive today.

Honda NSX


The Honda NSX has a 3.5-liter twin-turbo petrol engine plus three electric motors (one at the back, one powering each front wheel) making a total of 573 horsepower.it has four-wheel drive and a 9-speed double clutch, paddle shift gearbox.

It costs £1,38,000 Around the same as the Porsche 911 Turbo S. And it has the futuristic lines you would except a rare-breed Honda. Power comes from a 3.5-liter twin-turbo V6. Backed by a squadron of electric motors. Together, they give the NSX 573 horsepower.

So you would assume the performance is something to shout about.

If you ask Honda for the technical information on this car, they will email you a file so enormous that it actually breaks the internet. And yet, nowhere in it does it mention the 0-60 time. They simply refuse to tell us what it is. This is a supercar. Its top trumps, isn't it? So an Auto Journalist has tested this car with a data logger. 




The Honda Nsx has done 0-60 in 3.2 seconds which means it isn't quite as fast as McLaren 570S or Porsche 911 Turbo S or a Ferrari 488 GTB. That's why they're not mentioning it. Honda is Happy to quote the top speed.which is 191mph but that too is slower than its rivals from Ferrari, Porsche, and McLaren. 


Honda took 10 long years to devolop the Honda NSX
So has the new NSX got anything in the performance department that makes it rise above its supercar peers?

well, yes, firstly there are the breaks, which are fly-by-wire. There is no physical connection to the pedal. That's because they have to harvest energy to recharge the battery system. it's a much clever version of that you get on the Porsche 918, a car that costs five times as much. Then there's the hybrid system. it uses not one electric motor, as you might except but three. And the way the Honda uses them is well good.


Although the Honda uses full brake-by-wire, the law demands that it can be defaulted to using a conventional hydraulic backup system if the electronics go wrong. which they probably won't, because it's Honda.

The one at the back is the wingman for the petrol engine, filling the power gaps when the turbos lag. This gives the NSX ballistic pick-up at any speed. But it's the two at the front that is the real party-piece because they drive a wheel independently of each other which this car has a sort of space-age four-wheel drive. And that means extraordinary things will happen when you drive it into a corner.  




When you are driving this car in corner computers will measure your speed, G-force, steering input and so forth. They are adding power to the wheel or taking away from the wheel as it's needed. Then you get perfectly flat, perfectly controlled corners.





The aerodynamics in this car are so clever they can cool all the motors while providing vasts amount of grip-enhancing downforce to the front and rear wheels. And it does all this without anything as old-fashioned as huge wings and spoilers.








Alfa Romeo 4C Spider


A symphony in carbon fiber. Balance Personified. A mini Ferrari as cute a bunny rabbit, with the greatest badge in the history of motors. 

Alfa Romeo 4C Spider has a 1.7 4-Liter 4-cylinder turbocharged Engine which makes 234 horsepower. It can go from 0-60 in 4.5 seconds and it has a top speed of 160 mph. It weighs 1128kg. It uses a carbon fiber tub, front and rear crash box, and hybrid rear subframe mainly out of aluminum to keep weight at 1,050 kilograms 

The entire carbon-fiber monocoque chassis ("tub") of the car weighs a mere 65 k. Front and rear aluminum subframes combine with the tub, roof reinforcements and engine mounting to comprise the 4C chassis giving the vehicle a total chassis weight of 107 kg and a total vehicle curb weight of just 1,118 kg.


 The 4C has a single carbon fiber body, similar to the body of many supercars. The outer body is made of a composite material (SMC for Sheet Moulding Compound) which is 20% lighter than steel. The stability is comparable to steel and better than aluminum.



Alfa Romeo 4C Concept is a two-seater, rear-wheel drive coupé with technology and materials derived from the Alfa Romeo 8C Competizione, with 1750 turbo petrol engine with direct injection, the "Alfa TCT" twin dry clutch transmission, and the Alfa DNA dynamic control selector.


Some of the Alfa Romeo 4C Spider interiors have been taken from other cheaper cars. Such as the Fiat Punto Hatchback.

Even though The Alfa Romeo 4C  won  'Most Beautiful Concept Car of the Year' award by the readers of German magazine Auto Bild.

Porsche 911 GT3 RS


Porsche 911 GT3 RS has got an incredible engine with no turbocharger with just 4-liter flat six, but you get a 500 horsepower.  It has a maximum of 9000 rpm. It can go 0-60 in just 3.3 Seconds. It has got a top speed of 193 mph. The rear wheels are driven through a seven-speed dual-clutch automatic or an optional six-speed manual transmission.
It has fattest back tires for a road car. It has scaffolding in the back for stiffness, carbon-fiber body panels for lightness. The roof is made of magnesium, so if you turn it over and there are sparks, there will be a blinding flash of light, and then you will be having a convertible.


With its carbon-fiber rear ironing board, larger front spoiler, front fender-top vents, and new rear underbody diffuser, the RS produces double the downforce at 124 mph of the already pretty downforce-y standard GT3. 
The vents over the front wheels on Porsche 911 GT3 RS double the amount of downforce over the front axle, balancing the mighty rear downforce of that massive rear wing.

The engine has more swept volume and lower-friction internals, and offers more revs, sharper response and increased outputs.
The biggest changes center on the chassis and aerodynamics, plus greater scrutiny applied to weight savings, as befits the RS moniker.  Stiffer springs (double the rate of the previous RS at the front end, 50 percent up at the rear) deliver sharper responses and increased feel, the trade-off being a slight loss of ride quality – a sacrifice Porsche believe RS buyers will be happy to make
Porsche 911 GT3 RS  can handle corner amazingly because it has got a four-wheel steering, the engine is sitting over the rear axle which gives an astonishing grip.

Porsche 911 GT3 RS has intake air booster which helps to increase up to 20 horsepower. 
The RS’s look is, er, extroverted. Low and wide and accented with exposed carbon fiber and various aero addenda, the thing is never going to be pretty. But it is purposeful in appearance, and RS cars have always been the outgoing sort, offered in eye-popping color combos.

           

Dodge Challenger SRT Hellcat


The Dodge Challenger SRT Hellcat has a 6.2 Liter supercharged Hemi V8 engine with 707 hp. It can go 0-60 in 3.6 seconds with a top speed of 199 mph. It has a humongous Torque of 881 N-m which can pull a jet at a speed of 100kmph.

The Dodge Challenger SRT Hellcat has got big bass rumble and roar with 6.2 Liter V8 Hemi. And over the top the shrill manic whine of a supercharger. It takes 80 horsepower just to drive the supercharger. Neither is it a particularly economical one.

The SRT Hellcat engine is so powerful during development the manufacturers had to upgrade their engine test rigs or they would have torn to pieces.



The Hellcat is based on the old Chrysler 300c. And Chrysler 300c underneath is a 1990’s Mercedes E-Class engine.

The Challenger Hellcat has a power to weight ratio of 2.81 kg per horsepower.

The Dodge Challenger SRT Hellcat has a three-mode adaptive suspension for normal, sport, track. Buyers can choose a choice of a rev-matching eight-speed automatic or six-speed manual transmission

Despite having a powertrain that can burn a whopping 5.6 Liters of fuel per minute, when not driven like an utter maniac, it can still return an impressive 8.5 Kilometers per Liter on the freeway. At full speed, it'll drink it's 70 Liter Petrol tank in just 13 minutes.

And in fact, it needs lots of air to mix with all petrol it's drinking, so manufacturers had to remove one of its headlights and replace it with ram air intake to feed air to the engine. So they swapped eye for a nostril which resulting in more torque. You can see it clearly in the image below.


The SRT Hellcat is equipped with two separate key fobs; use of the "black" fob limits engine output to 500 hp (370 kW), while the "red" fob enables full output capability.



On the performance mode screen in the SRT Hellcat, you can measure G-forces, Braking distances, Reaction time, Lap history.

The Dodge Challenger SRT Hellcat costs Around ₹69-75 Lakhs.




           

Car You Should Know : Aston Martin Vulcan


Aston Martin Vulcan has a 7 Liter V-12 Engine with 820 horsepower with a 6-speed sequential transmission. It can go 0-60 in 2.9 seconds. It has a top speed of 208mph (with rear wings). This Car is a limited edition only 24 cars were produced. This car was launched in 2015. 

This car has got 3 power modes which allow you to set at a minimum, moderate and high-performance modes. At minimum performance mode, the car releases 500hp. At moderate performance mode, the car releases 720hp. At high performance mode, the car releases Full 820hp. 


Even at slow speed, the engine is quite loud. The noisiest part the car, however, is not the engine. The breaks are the loudest it's like you are stamping on a piglet. This car produces lot's of noise, vibrations. 

In this car, you cannot wind down either of the windows. It has not got any accessories like sat-nav, radio. it has only got half steering like F1 cars. But sadly this car has no handbrake. This car is not road legal.


However, there is one amazing thing you get for £1.8 million. An all-expense paid trip to race track of your choice, Where Aston Martin test driver will teach you how to drive your car. Aston Martin company allots you a personal engineer for 24/7 assistance. 



This car releases flames from both sides at doors.

Aston Martin Vulcan has its own air jacks 



To make road legal this car has undergone with a series of modifications. Here are some 

  1. They have increased the height of the car
  2. The 7.0-litre naturally-aspirated V12 is remapped for emissions.
  3. The cooling system is replaced with a different unit for better temperature control. 
  4. The car's gear ratios are altered, and the clutch was changed to make the launch easier than the regular Vulcan.
  5. Spring rates and damper rates have been changed, and ride height lifting has been added to allow for easier driving on the road. 
  6. The steering lock became less limited to allow the car to steer more and give a smaller turning radius.
  7. The rear bumper has been modified to allow for a Euro-spec registration plate to be installed, along with plate lights, and a reflector.
