Tesla Roadster Origins
Every carmaker attempts to change and revolutionize the way vehicles are made, and how they run. Very few truly go out on a limb and try something new like Tesla Motors. This company actually tries to make something old work for the modern age. The company, named after the famous Nikola Tesla, dedicates itself to producing well-made and efficient electric cars. Created by some of the most forward thinking people of the technological age, and backed by noted names as well, Tesla focuses on making electric cars that are fun to drive and travel long distances easily.
As a new company, Tesla doesn’t have a great many cars to choose from, but those that do exist maintain the idea that the only reason people don’t buy electric cars is because most of those models lack features and abilities found in gas engine options. The company’s team of experts creates a car with longer distance abilities, shorter charging times, and higher performance than has ever been seen with an electric car. In the end, Tesla presents its first car to the automotive world, the Roadster.About the Tesla Roadster
Like any new high-end toy, the Tesla Roadster comes with a high price. Among its other attributes, the car’s price certainly turns heads. Naturally, when a company only produces a few units of a vehicle, especially with such unique technology, the price goes up. These cars are not ready for the general public yet, but Tesla works towards a goal of creating a well-made, affordable electric car for the average consumer as well. In the meantime, the Roadster provides a great choice for those who can afford it and want to help this car make its name.Tesla Roadster Features
The Tesla Roadster, released for the 2011 model year, is more than just a pretty face with a unique fueling system. This car is exactly what it looks like, a sports car with plenty of power and precision to back it up. The Tesla Roadster comes in two trim levels: the base 2.5 and the 2.5 Sport.
Like any other sports car choice, the Tesla Roadster offers plenty of amenities to keep the driver happy. However, it lacks space. This two-seat convertible offers tight quarters inside the cabin, and with the roof on, getting in and out of the car proves a challenge for most people. Once you get past the cramped interior though, the car features leather upholstery, a touchscreen electronic interface, and a four-speaker sound system among its many amenities. The 2.5 Sport also offers forged alloy wheels, a different suspension system option, and more power.
The battery pack in the Tesla Roadster is the result of innovative systems engineering and 20 years of advances in Lithium-ion battery technology. The ingenious pack architecture enables world-class acceleration, safety, range, and reliability. The pack contains 6,831 lithium ion cells and is the most energy dense pack in the industry, storing 56 kWh of energy. Roadsters are engineered to charge from nearly any 120-volt or 240-volt outlet. Most Roadster owners find they rarely use a complete charge, and charging each night means their car is ready to drive 245 miles each morning.
Under the hood the Tesla Roadster won’t disappoint either. It comes equipped with a 375-volt AC-induction engine capable of 288 hp and 273 lb-ft of torque. The engine on the Sport model has a bumped up torque of 295 lb-ft. The electric engine pairs with a single-speed transmission system. The 2.5 Roadster goes from zero to 60 mph in about 3.9 seconds by Tesla’s estimation, with the Sport version coming in about .2 seconds faster.
The regenerative braking system, completely independent of the brake pedal and brakes, is controlled by the Power Electronics Module. The drive experience is similar to engine braking or downshifting in a gas-powered car. The electric drivetrain instantaneously switches from “drive mode” (forward torque) to “generating mode” (reverse torque) based on the throttle position. When the Roadster was first in development, test drivers worked with the firmware team to fine tune the amount of regenerative braking to optimize both vehicle stability and range. Much higher regenerative torque levels are possible, but could result in loss of traction and a less manageable sports car. Alternatively, less regenerative braking returns less energy back to the battery during stop and go driving, resulting in decreased driving range and overall efficiency.
