Could this be the next-generation Toyota Vios we see here, spotted testing in Thailand? Photographed by a Headlight Magazine community forum member, the images show a disguised B-segment sedan and hatchback in separate sightings.

Here, what’s anticipated to be the upcoming Yaris Sedan for the Thai market appears to adopt a look which rather resembles the Corolla Altis in its headlamps and tail lights, from what can be approximated through the camouflage. A shark-fin antenna sit atop the roof on both sedan and hatch test mules, replacing the pole unit on the existing model.

On both sedan and hatch, the C-pillar window kink is now slanted forwards slightly. The sedan mule gets a rectangular fuel filler flap compared to the current car’s round item, while the hatchback retains the round fuel flap, and now appears to adopt a split-tail lamp cluster arrangement.

According to the forum post, the upcoming Yaris Sedan is expected to make its Thai market debut in the second quarter of 2017 (which is very soon), with the accompanying hatchback expected to follow later on in the third or fourth quarter this year.

Under the hood, the next Thai-market Yaris Sedan/Vios is tipped to house the 3NR-FE petrol 1,197 cc inline-four engine (to get Thailand’s eco car tax incentives) with Dual VVT-i, producing 86 hp at 6,000 rpm and 108 Nm of torque at 4,000 rpm, driving the front axle via a continuously variable transmission.

This unit is perhaps unlikely to feature in the future Malaysian-market Vios, which should retain its current 1.5 litre engine – updated to a new Dual VVT-i unit last year.
