Tesla Model X May Be Significantly Cheaper than the Model S

According to the report from PCMag, the upcoming Tesla CUV – the Model X, will possibly carry a base price of “only” $55,000, compared to Model S base price tag of $62,400 (both with the $7,500 federal tax credit taken into consideration). This is an approx. 12% price cut.

At the same time, opponents are reasoning that, without dealer...

Insider information indicates some new engine options, including a 2...

Automobile Suspension Design 101 (Part V): H-Arm Suspension

In this section, we will take a look at the last type of automobile suspension, which is usually used for rear wheels.

In the H-arm system, one end of the arm is connecting to two locations of the car body; another end connects to two locations of the wheel hub. The H-arm alone can limit 4 degrees of freedom, so it need another horizontal control arm to limit one more degree to make the whole system with 1 degree of freedom.

However the above design has non-optimal wheel movement trajectory, most automaker will not use such design without modifications...
