In summary, the Lingenfelter 427TT was tested by a magazine and achieved a 0-60mph time of 1.97 seconds. A video of the car in action can also be found online. However, based on calculations and assumptions made by a researcher, it is unlikely that the car could achieve this level of acceleration due to limitations in traction and power.

http://www.motortrend.com/features/performance/112_0304_fast/index.html magazine tested it and did 0-60 in 1.97s.

http://co-project.lboro.ac.uk/users/cowy2/hostedstuff/lpe-8secVette.mov is a video of it.

This is something a mate worked out, is it accurate?
----------------------------------------------------
== Part 1 ==
0-60mph in 1.97s
Skid pad = 1.01g
Curb weight = 33 401lbs = 1 514.99kg
60mph = 96km/h = 26.7m/s

v = u + at
26.7 = 0 + a1.97
a = 26.7/1.97 = 13.53m/s
.'. 13.53/9.81 = 1.37g
.'. Need 1.37g on skidpad to accelerate that fast.

== Part 2 ==
Assuming no mechanical losses from tyres and all wheels get 100% traction, coefficient of friction u (mew) (rubber to concrete) = 1 (dry).

u = 1
F = uN
N = 1 514.99 * 9.81 = 14.86kN
.'. F = 1 * 14.86 = 14.86kN

.'. Force achieved from vehicle is 14.86kN.

Force needed from vehicle to accelerate perfectly:
F = ma
F = 1 514.99 * 13.53
F = 20.49kN

Conclusion: Impossible, unless powered by jet engines!
------------------------------------------------------

So anyone got any ideas?

The skidpad test is apparently based on a 200ft circle laptime rather than linear acceleration. It's entirely possible (probable even) that a car has better forward/backward acceleration than lateral acceleration capability.
 

Related to Can this car really do 0-60 in 1.97s?

1. How is it possible for a car to reach 0-60 in just 1.97 seconds?

There are several factors that contribute to a car's acceleration, including its weight, horsepower, torque, and design. A car with a lightweight body, high horsepower and torque, and aerodynamic design can have a faster acceleration than a heavier, lower-powered car.

2. What kind of engine does this car have to achieve such a fast 0-60 time?

The type of engine can vary, but most cars with a 1.97 second 0-60 time tend to have a high-performance, turbocharged engine. This allows for a quick burst of power and acceleration.

3. Are there any special modifications or enhancements made to the car to achieve this speed?

Yes, in most cases, cars with a 1.97 second 0-60 time have been modified or enhanced in some way. This could include changes to the engine, transmission, suspension, and other mechanical components to improve performance.

4. Can the car consistently reach 0-60 in 1.97 seconds?

The car's ability to consistently reach 0-60 in 1.97 seconds will depend on various factors such as road conditions, temperature, and driver skill. However, in ideal conditions, these high-performance cars are designed to reach 0-60 in 1.97 seconds on a regular basis.

5. Are there any safety concerns with a car that can reach such high speeds?

As with any high-performance vehicle, there are always safety concerns to consider. These cars are designed to handle high speeds, but it is important for drivers to follow all safety regulations and use caution when operating a car with such fast acceleration.
