Our other man in China, (the Dutchman, not Bertel) has some spy shots of a new General Motors EV. It looks like a Chevrolet Sail, but may not be dubbed as such.

The mystery EV in question appears to wear “Springo” badges, and this would have some precedent, according to Tycho from Carnewschina

“When the ‘Sail EV’ debuted as a concept on the 2010 Guangzhou Auto Show it had a new S-shaped logo on the bonnet, leading the intense speculation that Shanghai-GM was planning a green-energy brand.”

Piston Slap: Being On The Level With One’s Self Wed, 09 Nov 2011 15:41:54 +0000

Dear Sajeev,

I need your help again. I live in Colombia and, as you already know, I am the owner of a 2000 Subaru Forester (the 2.0 EDM model). This particular model has rear self leveling struts and recently they went bust. My dealership is asking 4 million pesos (about 2235 USD) for the replacements. I really think it’s a little bit steep so I’ve been searching online but haven’t been able to find the OEM parts. I read on a forum ( that you can put the non-self leveling struts. Is this a good idea? How much would the driving characteristics of my car change? If I go this way, what other components of the suspension should I replace? Thanks in advance for your help.

Sajeev Answers:

Oh yes! This is the age-old query of removing a factory self-leveling system for something more mundane, quite affordable and probably adequate for anyone’s needs. In theory, these systems are entirely interchangeable with a conventional damper, as the self-leveling feature only comes into play when the rear of the vehicle is loaded down. In practice, there might be a different spring to go with the unique strut.

That said, don’t always trust what you read on the Internet. Look up the part numbers to make sure there aren’t two different springs for the Forester. Once that’s cleared up, go ahead and eliminate the self-leveling feature: while a great idea when new, it loses a lot of luster once the miles rack up, the complicated bits wear out and the vehicle depreciates to the point where spending thousands on a repair simply makes no sense.
And this isn’t a unique situation: people have eliminated air suspension systems for decades on depreciated iron. Switch using OEM Subaru parts and you will be just fine. Or maybe the correct Subaru spring with a new set of four aftermarket dampers from a sportier vendor like Bilstein, Koni, etc. Unless your roads are pretty rough, then stick with the stock shocks for minimum abuse over potholes.

And your wallet will appreciate it, with little to no detriment to the Forester’s performance. Perhaps the ride will gain a little harshness, but I have my doubts: fully-air suspended cars are more susceptible to this.  I would have no concerns whatsoever with this swap.

Unless you are a chronic “overloader” of rear storage compartments…then you might want to buy the self-leveling bits online and find a local mechanic to install them for you.

So now you know, good luck with your decision.

March 20, 2010.  Spring Equinox. Spring has sprung. How could celebrate the first day of spring 2010 better than with a concise pictorial history of springs?

Apart from tires and seats (which typically have their own springs, the seats, not the tires) the car’s suspension is what protects your (personal) rear end and spine from the rigors of the road. Apart from shock absorbers (which we’ll celebrate the minute we’ll find an appropriate season for shock absorbers), springs are an essential ingredient of your suspension. Springs come in three basic flavors.

The common leaf spring has been in use in cars and trucks into the mid eighties. From then on, they became an object of derision, except on heavy duty trucks, which use them to this day. The leaf spring was also called “carriage spring,” because it is as old as the horse-drawn carriage. Hence its humorous effect.

To the untrained, a coil spring seems to be the most logical choice. It’s inbred: Most of us have been created with some type of coil spring involved. (See picture left.) To remove or to install a coil spring, you need to be able to operate a coil spring compressor tool. If you don’t know how to operate it, this can have similar effects as a coiled snake. The coil spring is sometimes used in combination with the leaf spring. Or with a shock absorber inside. We’ll get to that later. There are many other coil springs in your car, from valve springs to the spring that pulls your accelerator back – or not.

Then there’s the torsion spring, that strange contraption I learned to hate when I was a young copywriter and they threw me on the Volkswagen account. Die Drehstabfeder or Der Torsionsstab is (so it has been drummed into me) basically a rod that twists along its length. It was popular in the VW Beetle, in the Porsche 356, in the early Barockengel BMW 501/502, in early Porsche 911s, and several Chrysler and GM cars. To this day, I don’t understand why one would twist a poor old rod if there are springs. To this day, they use torsion bars.

From here on, we get into more complex matters, such as coil-over-oil, (or possibly coil-over-gas, but it doesn’t rhyme). It is a combination of a shock absorber and a spring, also known as a McPherson strut. When I was a young copywriter in 1973, this was a big deal. Later, they confused me completely by combining a McPherson strut with a double wishbone suspension. At that point, I turned into a Creative Director and was above such minutiae.

This concludes our TTACesque celebration of the Spring Equinox. May the sun shine bright on you, don’t forget to change the winter tires, and  give your car a good rinse to get the salt out.
