Though there are alot of people that would want this car to come over unchanged, if GM and Saturn are thinking about bringing it over, there are some common sense changes that would have to be made
The styling seems ready made to come over as a Saturn. So there really arent any changes needed there, except for whatever is needed for bumper standards.
I went to the website and got the dimensions for this van because many people seem to be confused about the size of the van, which is hard to determine from just photos.
The Zafira is actually quite small....
The length of the Zafira is 175.9 inches long which makes it much smaller than the Uplander/Relay/Terazza CSVs' which are 204.9 inches long, it actually is smaller than a Cobalt or an ION whch are 180 and 184 inches long. The closest thing that I found to the Zafira in length is a Focus wagon which is 178 inches long. At 65.7 inches high the Zafira is tall, though lower than a CSV which is 70 inches high, which is why I dont think that it will make a decent Vibe replacement.
The Zafira is 70 inches wide, which makes in narrower than the already narrow CSV's which are 72 inches wide, but it's a little wider than a 67 inch wide Cobalt/ION.
For comparison the Zafira is a little smaller than even the Mazda 5 which is 181 inches long, but taller than the 5 which is 64.2 inches tall and wider than the 69.1 inch wide 5.
The Mazda does offer a sliding side door where the Zafira has conventional style doors, which have never been a big hit in the US market with mini-van buyers, see: Colt Vista, Mitsubishi Expo, Honda Oddessy/Isuzu Oasis. Saturn should consider sliding doors as a possible design change.
Performance is another issue, the base model 1.6 litre Zafira takes 13 seconds to get from 0-60, which is pretty darn slow, the Zafira with the engine closest to what would be offered in the US is a Zafira with the 2.2 litre Ecotec and that one takes 10 seconds to get from 0-60, now I am not saying that this thing should be cracking off 4.6 second 0-60 runs, but something in the 7 to 8.5 seconds, maybe even 9 seconds would be a little better. I am guessing that the American Zafira would have to come standard with the 2.4 litre VVT ECOtec 4 cylinder from the Solstice, which makes 177hp. The Mazda comes with a 2.3 litre with a 157hp.
The performance for models with the 1.9 litre diesel engine are not that bad for a MPV, they go about 11 seconds from 0-60.
The best performing Zafira is the VXR model, which runs impressive 7.2 second 0-60 times, but it is the mose expensive model in the line.
The Zafira does also have a small gas tank for US consumption, it is 12 gallons, which makes it smaller than 13 gallon tanks on the Cobalt and ION, and smaller than the 15 gallon tank found on the Mazda 5.
Price is another issue, given current exchange rates, Pound for Dollar, the base 12,995(Pound) 1.6 litre Zafira is $22,997 in USD, and the top of the range Zafira VXR goes for 21,995(Pounds) in the UK, which would make it a $38,924 MPV over here! Yikes, thats Yukon money. (And thats for the base model, I built up a loaded 28,270Pound VXR with color nav, DVD, park sensors, 19 inch wheels,etc....thats a $50,029 in USD)
The Mazda 5 starts at $17,435, a base Chevrolet Uplander starts at $21,250. For Saturn to really make the Zafira work, it would have to, ideally, undercut the price of the 5 and start at $16,995 for the base version, and top out at no more that $25-26,000 for the top of the line models. Saturn should offer a VXR style RedLine edition with the 205hp Supercharged 2.0 litre ECOtec, again, no more than $25,000-$26,000.
