Default Ground clearance and trunk capacity ?

Hi all, Im about to buy a Q30 and Im still puzzled about a couple of things : ground clearance and trunk capacity. Granted, this is not of earth shattering importance but since, overall the car ticks all the boxes, at least mine, those two are bugging me.

Re. ground clearance, the Infiniti brochure does not specify anything while different websites indicate 7.5 to 8.3 in.

Re. trunk capacity, the Infiniti brochure specifies 15 cu ft. whereas all websites state a capacity of 13 cu ft.

Where is the truth ?

I personally would go with what the Infiniti brochure says.

The Q30's ground clearance is 7.5 inches and the QX30 has a bit more ground clearance than the Q30. That may be where the confusion is coming from so if you want to sit a bit taller than the QX30 may be the way to go. As for the cargo capacity, it should be 430 liters so that's around 15.18 cu ft. Maybe the larger luggage volume is when the seats are folded down?

Thanks Indiana, 7.5 inches is good enough, on a par with most SUV bar the Mazda CX5 and Subaru Crosstrek. In fact when I tested it, I had a similar feeling, in terms of ride height and headroom, as when I tested the Subaru which has a record 8.7 ground clearance and is, like the Q30, not very tall overall. In fact it felt so good that I just ordered the Q30 anyway.

I finally found the true figures given by the designer himself, Alfonso Albaisa, Infiniti Executive Design Director :

"The Q30 Premium's elevated stance (170mm at the front axle) allows for a higher hip point (531mm), which aids ingress and egress. The A-pillar design is intentionally slim, contributing to enhanced visibility for a confident driving experience. Q30 Sport stands a little lower (155mm at front axle), providing for agile ride and handling.

The Q30's coupe-like design belies its interior space and functionality. Cabin room is highly competitive, notably the boot capacity of 13 cubic-feet (368 liters VDA), which ranks among the best in the premium compact egmnt."

170 mm is 6.7 inches
I found out that VDA is a german standard for cargo calculation using wood blocks of 1 liter volume each and it is just possible that 368 VDA liters translate into 430 liters

Glad we got some slim pillar but that might not be a good thing come time to see a frontal crash test, last thing i'll want to see is that front pillar be compromised. But as far as i've seen, Infiniti has had a good safety history. Anyone concerned about this?

I'm not too concerned considering it's listed as the safest car in the small family car segment. http://www.infinitiq30.org/forum/q30...r-segment.html

Guess most drivers don't really feel marginal ground clearance height differences like the 2 inches between the Q30 and the Subaru Crosstrek.

Besides the obvious advantage of off-road capability (which also of course largely depends on other characteristics of the vehicle), a high ground clearance naturally provides a high ride which is comfortable in heavy urban traffic as it makes you feel kind of "above the fray".

The Subaru Crosstreck is a case in point; it is the archetype of the Crossover, i.e. very capable off-road while also very competent on roads and motorways, thanks to its unusual engine architecture (flat four boxer engine) which provides a very low center of gravity despite the vehicle high ground clearance. A pity its petrol engine is not turbocharged and its automatic gearbox is a CVT, otherwise I would have bought it without hesitation.

Coming back to the Q30, it shares some similarity with the Crosstreck in the sense that they are both kind of sporty-ish looking cars with an elevated stance, although of course with infinitely more elegance and class in the Q30 case.

Now I would agree with Indiana that the ground clearance height difference is relatively meaningless for the majority of drivers (who don’t contemplate going off-road anyway and certainly not with a Q30), except for this not unpleasant “above the fray” feel.

That “above the fray” feel may be exatly why more and more buyers are moving towards CUVs and SUVs, that's certainly one of the main reasons why I would choose those segments of sedans. And of course the additional cargo space.

While the Crosstrek may be more off road capable, it's certainly no looker compared to the Q30 and the most off road I'll probably ever go are those somewhat uneven and packed dirt roads.
