The real reason to make it a four door is to make the Volt rebadge operation cheaper. This is GM we're talking about.

Exactly! I was wondering the same thing.

2007 Prius: 96.2 ft3 interior volume, 16.1 ft3 cargo volume
2007 Mini: 76 ft3 interior volume, 4.7 ft3 cargo volume

These cars are in different classes entirely, so this comparison is misleading. If anything, the Mini should be ashamed that even with start-stop and diesel it hasn't surpassed the Prius, which is more than 25% larger.

MDGrape-3 will never top the supercomputing charts - it is not a real supercomputer. Instead, it is a special purpose machine built solely to run ONE very specific program. This article never should have been posted - the claim that MDGrape-3 will top the supercomputing charts is just as wrong as saying that Intel & AMD are about to be upstaged in processor performance by a GPU from nVidia. Sure, a GPU can push more polygons than a CPU. But try websurfing on a GPU - it just won't work. GPUs are built specifically for Graphics, just like MDGrape-3 is built specifically for Molecular Dynamics. MDGrape-3 can't even run the benchmarks needed to get on the supercomputing charts.
