Okay...globally, things change as apparently Suzuki-Maruti sells a ton of small cars, especially in India. So, actually, in terms of numbers Suzuki sells far more.
That said, the obvious 4x4 markets are US and Australia. And even globally, Subaru's 2016 net profit of 3.2 billion USD was much greater than Suzuki's, which was under 1.5 bln USD.
I am glad Suzuki is doing well overall. A 1.5 bln USD net profit is not bad at all. It is actually impressive as it comes from small cars.
Obviously, there is practically no overlap not only in vehicles, but also in markets.
While we are on it, Mitsubishi is another Japanese company that used to be in the same boat as Subaru and Suzuki in the US. It still lingers around, selling 100,000 in 2017, which is but a fraction of Subaru's 650,000 (btw, Ford sold 900,000+ F-series full size trucks in 2017).
More fun:
2006:
Subaru: 200,000 vehicles. -500,000 compared to 2018 projection.
Suzuki: 100,000 vehicles. left market
Mitsubishi: 120,000 flat in 2018 vs 2006
I am surprised Subaru sold as much as Suzuki and Mitsubishi combined already in 2006 when it was considered a quirky, niche car-maker. Apparently, Mitsubishi peaked in the early 2000s, selling 300-350,000 per year, then nosedived in 2004 and never recovered. Suzuki actually only cracked 100,000 twice, 2005-6.
Subaru was solidly above 100,000 already in 1978 but while it toyed with 200,000 a couple of times, really had issues stabilizing around that number till the 2000s and, of course, its march north of 200,000 units per year only started when the 2009 Foz and the 2010 Outback kicked off the new Subaru era.
