While measuring bumpers and mirrors is a lot of fun, it's actually where they put the axles, tires, and roof that is the best measure of relative 'box' size for the interior seating. Efficiency of layout comes into play, but it's hard to use room that isn't there. The i-Pace is a cab forward design with an extended wheelbase.

The Model 3 is closer in size to a Civic than to an i-Pace. But nobody is going to know until both cars are out there. There are more Model 3's on the road than i-Paces, but neither is available for sale to ordinary consumers.
It's not quite that simple either. The Model X has a slightly shorter wheelbase than the iPace (117" vs 118") but is considerably larger in every other dimension i.e. track 67" vs 65", height 66" vs 62", overall length 198" vs 184". The third row seats in the X are more or less directly over the rear axle too, so there is cabin space well beyond the wheelbase. Luggage space in the X is way bigger than the iPace (2487 litres vs 1453 litres with seats folded), which gives you some idea of the comparative volume rearward of the front seats. The Model X is actually one of the biggest cars in its class. Bigger than a Volvo XC90, BMW X5, Audi Q7, Porsche Cayenne andVW Touareg. The iPace is a full class size smaller, although that represents a bigger market share in Europe. The Model X is simply too big for many European buyers, but great if you need the extra space. Our kids love travelling in the X as it has so much room in the middle row with the bench fully rearward and plenty of luggage space with the rear row folded. Headroom is great too, only slightly restricted in the third row with the sloping roofline. The iPace is going to feel much smaller inside for sure.
