      Facelifted Toyota Yaris revealed - Gains new 1.5-liter engine, water-cooled exhaust manifold

      TOYOTA LINES UP NEW 1.5 PETROL ENGINE FOR YARIS
      New ESTEC unit promises stronger performance and improved emissions and fuel economy

      Toyota is introducing a new 1.5-litre four-cylinder petrol engine to the Yaris range to replace the current 1.33-litre unit, offering not only more power, more torque and faster acceleration, but also improved fuel economy and lower CO2emissions.

      Developed in anticipation of the future Euro 6c emissions standard and RDE (Real Driving Emission) homologation requirements, it is a member of Toyota’s ESTEC (Economy with Superior Thermal Efficiency) engine family. It benefits from new technical features that deliver better performance and a more enjoyable drive, while at the same time achieving a reduction of up to 12 per cent* in fuel consumption, under current NEDC official test criteria.

      The new unit is being manufactured by Toyota Motor Industries Poland as part of a €150 million production investment programme by Toyota Motor Europe.

      In Yaris the naturally aspirated 1,496cm2 engine develops a maximum 110bhp/82kW and peak torque of 136Nm at 4,400rpm. Its responsiveness ensures a comfortable drive both in urban traffic and on the open road. Compared to the 1.33-litre unit, it is 0.8 seconds quicker in acceleration from 0 – 62mph (11.0 versus 11.8), while at overtaking speed the improvement is more than a second, moving from 50 to 75mmph in 17.6 seconds compared to 18.8.

      Meeting the challenge of emissions and fuel economy

      Toyota’s world-leading experience in hybrid powertrain technology has proved valuable in addressing the challenges presented by the new Euro 6c emissions standard and RDE homologation cycle, witnessed in the new engine achieving a 38.5 per cent thermal efficiency value, placing it among the best on the market. This has been achieved by using a high, 13.5:1 compression ratio, adopting a cooled exhaust gas recirculation (EGR) system and extending the variable valve timing operation so that the engine can switch from the Otto to the Atkinson cycle to gain optimum efficiency in different driving conditions.

      The higher compression ratio has been made possible by the combustion chamber design and new pistons, which promote a homogenous air/petrol mixture and rapid combustion. Cooled EGR reduces combustion temperature and also helps prevent the occurrence of engine knocking. Furthermore, the volume of reinjected inert gases allows for a reduction in pumping losses at low and medium loads, improving overall engine efficiency.

      The adoption of a new variable inlet valve timing system – VVT-iE** – allows the engine to switch from the Otto to the Atkinson cycle (and vice-versa) in a fraction of a second. Controlled electronically, closure of the intake valve is delayed, reducing the compression phase and further helping reduce pumping losses (Atkinson cycle), and enabling a prompt return to the Otto cycle for better performance under high loads The phase shift of the exhaust camshaft is hydraulically controlled.

      Toyota’s first water-cooled exhaust manifold

      The engineers also focused on improving fuel consumption at sustained motorway cruising speeds, leading to the use – for the first time on a Toyota – of a water-cooled exhaust manifold. By limiting the gas temperature, this avoids the need for mixture enrichment to reduce combustion temperature at any motorway driving speed. As a result, both fuel consumption and exhaust emissions are reduced.

      In common with other Toyota ESTEC engines, the 1.5-litre unit benefits from the latest measures designed to reduce friction losses.

      The mono-wiper lives! Interior is the same and the engine looks interesting but not too fun. Are we getting the refreshed Yaris here (especially that turbo one)?

      Side note: our Corolla has those circular HVAC vents and they are a pretty neat design. Instead of a single flap that flips over to block airflow, it has five or six petals that swing around together (controlled by the center knob) to close it off. It kind of looks like the aperture in a lens closing up.

      overall, I find yhis new yaris encouraging...more mpg without a loss of peppiness...

      I do like the range of motion offered by a round vent. As a kid thought 90s Pontiacs were cool because of that.

      The front end actually whizzes right past ugly and into hilarious. Seriously, I laughed when I saw it.

      Its like when a cute little 3 y/o gets really angry, but the look is just so funny you have to laugh.

      Overall, not bad at all. Not liking the fakey vents on the rear bumper skin, and I'm not feeling the front end, though. The interior seems nicer than I thought it would be, I wonder if the materials compliment the overall design, but I don't think they'd cheap out, given the number of markets the car is available in. Just because NA doesn't see merit in nice interiors on small cars doesn't mean others won't.

      Maybe the new engine will finally get better fuel economy than the Corolla.

      The Yaris desperately needs new transmissions.

      The stick Yaris does a lot better around town/in traffic since it is so light. I can drive mine like a tool on my commute and it will get 35-36 MPG (upper 30s if I baby it). The Corolla can get mid 30s around town but you have to drive with a light foot.

      Where the Corolla shines in comparison is on the highway -- the CVT has the revs at 1800 at 75 and it just loafs along getting upper 30s. With a taller 5th (or 6th) or if they ever get rid of that ancient 4-speed automatic, the Yaris would do a lot better on the highway. It gets low 40s at 55-60 MPH, upper 30s under 70 MPH and mid 30s at 75-80. Mine turns 3000 at 70 and 3500 at 80 -- a lot better than my old Hondas, and it has surprisingly good in-gear power, but I still wish for a tall cruising gear (don't mind downshifting to pass).

      It is one of the few that doesn't have one! Mine's in the speedo.

      No. The Yaris iA sedan (previously Scion iA) is the rebadged Mazda 2.

      I'm wondering how much the water cooled exhaust is going to help NVH. That said, in those markets where it's popular, modifying and tweaking the engine/exhaust just got much more difficult.

      Love it or hate it, that adds some character to it. I can't blame Toyota though for wanting to play it safe and sell their cars through their reputation for reliability and quality, instead of take a chance with styling:

      This is the 2nd facelift of this generation Yaris/Vitz, which was in itself just a moderaly revised previous gen Yaris/Vitz. The economic of B-cars must be really grim on a global basis if even Toyota can't justify new models every 5 or 6 years. I was expecting TGNA Yaris to debut this year but looks like that got scrapped.

      Probably not worth it given the razor thin profit margin.

      You'd think that the Yaris facelift was done to steal away some of the Honda Fit success. But, I can't say that Toyota will succeed. At least maybe not in the US.

      Honda Fit still looks better:
