2010 Mazdaspeed 3 vs. 2009 Subaru WRX: Head-to-Head Comparison

Since this doesn't really exist online, I figured I'd make it so that I had something at which I could look when considering what I might buy at some point.

I also read some of the reviews on each of these cars to see what professional drivers think of them.

On the Mazdaspeed 3, Edmund's noted that it's not as quick from 0-60 as the previous generation. The reason, apparently, is that Mazda tried to do something to dampen the torque steer inherent in the Mazdaspeed 3. As a result, it doesn't shift as quickly. They also say that won't rotate off-throttle. It is very stable in turns, and handles very well.

On the Subaru WRX, Edmund's says that turning is a little "doughy," but that you can rotate off-throttle and get good grip when exiting a turn. It seems from the comments that, despite not being the most precise handling, Edmund's likes it.

It's worth noting, however, that Motor Trend got wildly different numbers in some cases. They had the Mazdaspeed 3 at 5.6 seconds 0-60 mph, and the WRX at 4.8 seconds 0-60 mph.

In any case, it looks like the Mazdaspeed 3 has stiffer, more responsive suspension and costs less, whereas the WRX is faster in general, with more "give" in the drivetrain.

Configuring them to be as identical as possible, the WRX would cost $27,041 to have the same base feature set as the Mazdaspeed 3, and would not include a navigation system or a premium sound system. The Mazdaspeed 3 with the tech package includes those features, and costs $26,040, but lacks all-wheel drive. Objectively speaking, that's the difference. I haven't driven either, though, so I don't know which I would like better subjectively. The Mazdaspeed 3 has a better feature set. For $1,001 more, the WRX has all-wheel drive and is generally faster.

An Iota of Random

I am just about certain the world is going to stop rotating on it's axis, revolving around the Sun, and spin off into space in the very near future. Why am I so certain? The girl likes a car, and a good one at that. The new Subaru WRX, of all things. I hadn't seen the sedan model of the WRX until yesterday. The old model didn't do anything for me, but the new one is not bad. And she likes it, which, corresponding to me liking a car, happens once in a blue moon. And I like it, which is pretty much a major statistical anomaly, and may cause some strange event that could end creation in its entirety. Remember the Babel Fish? It's like that...

And then there's compilers. I dig 'em. But they're a pain in the keister, too. A book about ANTLR was just reviewed on Slashdot, and I'm curious. The reviewer goes on to say that the book talks about compilers in general, and so I'd like to see what best practices could allow me to avoid shooting myself in a foot again and damaging my remaining nine toes. I'm a fan of PLY just because I like Python (see half of the cartoons on XKCD for why). PLY takes Lex and Yacc, two of the more popular tools available for compiler-type people, and gives them the flexibility of Python. I'm pretty sure that, using these together, my computer might be able to figure out how to spout wings and fly all by itself in a line or two.

OK, off to vegitate...
