Just how similar are the two small, hatchback-like vehicles? Well, they are both owned, in a sense, by General Motors. But what else? Let’s have a look:

Upon first glance, there are many similar design aspects between Granite and Soul. Of course, Soul has already been in production over a year – where GMC’s “Utility Vehicle” is only in production phase. It’s not uncommon to see different auto makers steal…I mean share designs. Example: Honda Insight, Toyota Prius, and to some extent the upcoming Chevy Volt. But let’s look at the facts: “Prices at $13,300, the Soul base model comes with a 122-horsepower, 1.6-liter four-cyl – no automatic transmission is offered with the base engine. The other three Soul trim levels come with a 142-horsepower, 2.0-liter four cyl and a choice of the five-speed manual or a four-speed automatic. At its highest price ($18,900) you are still under $20K for the total Sports version with all available options.”

As for Granite – “Power for the Granite concept comes from a 1.4L turbocharged engine that is part of GM’s new family of small-displacement, highly efficient four-cylinder engines. It is matched with a six-speed transmission.” No word on pricing, but we are guessing Granite won’t break out of the $20 – 25,000 mark, if it wants to stay competitive anyway.

One major difference with Soul & Granite – Kia hasn’t taken the idea of suicide doors under consideration. But at 2010′s NAIAS rear-hung doors seem to be quite an eye-catcher. Whether or not they will remain in a final, practical, release model you’ll just have to wait and see.

Inside, the Granite concept dash looks more like something Harrison Ford should be piloting. Both Kia and GMC really enhance the appearance and usability of their interior compartments. Even base models of lower-end vehicles retain some sort of classy styling inside – materials cost money, but cool ideas are free flowing. We’ll wait and see what Granite ends up looking like, and how it will truly compare to Kia’s Soul.
