Car that carries high price tag is seldom subject to crash testing nowadays. This is partially due to the significantly higher expense for conducting such test. For example you will never see any Ferrari, Lamborghini, Rolls-Royces etc.,  in the US NHTSA, IIHS or Euro NCAP crash tests. This is also true for many Porsche models, including the Panamera.

At this moment, there is no official crash test conducted on the Porsche Panamera. However that does not prevent us to take a peek at how rigid is the Panamera’s safety cage during a frontal crash.

Yesterday, a man driving a Panamera lost control in the Los Angeles International Airport, and crashed then penetrated into Ter...

Porsche EV

Yesterday our source gave us some real interesting info which should put Tesla in a serious disadvantage: Porsche is working on an electric sports car, targeting at the Tesla Model S. Below image is the Porsche Panamera Sport Turismo concept (not the EV we are talking about).

The Porsche EV sports car we’re talking about will be smaller than its Panamera. This new model is previously rumored to be called the “Pajun”. Fierce competition in the mid-size luxury sports sedan lets Porsche make the decision that the smaller sedan to be in the form of pure EV only.

Since the Tesla Model S is about the same size as the Porsche Panamera, the new Porsche model will be s...

2015 Porsche Panamera Pricing

Most of you may have heard about the Porsche Panamera. In fact, even you don’t have enough money to afford one,  you can easily rent one from Hertz in almost all major US airport rental locations, see our earlier article here.

The last time I was at the airport, I asked Hertz for the price of renting a Panamera and they said it runs about $200 PER DAY, withOUT negotiation. I think you can definitely bring the price down further more if you haggle with them.

Suspension Design: Double Wishbone

In part II we briefly analyze the first type of suspension: trailing arm. Now let’s take a look at the second major type: double wishbone suspension.

This type of suspension uses two “A” shape arms, one place on the top and the other in the bottom. Because each A arm can limit 2 degrees of freedom, so the two A arms together limits 4 out of the total 6 degrees of freedom. Therefore we still need one more restriction to make the whole system to be 1 degree of freedom.

For front wheels, the extra restriction is the steering arm; for rear wheels, car designers usually use a toe angle control arm.

In the below chart, the one labeled...

Engines that the Porsche Macan uses have big story behind it. The future Audi cars may share something common with Porsche regarding these engines.

Currently there are two petro engines for the Porsche Macan: a 3.0L and a 3.6L, both are twin-turbocharged. These two engines have the same bore size (96mm), but different stroke (3.0L is 69mm, 3.6L is 83mm). Because of the smaller bore/stroke ratio, the 3.0L engine is more suitable for high revving purpose.

The 3.0L engine plays an important role in global market because many countries have heavy tax regulations on large displacement engines. By using the 3...
