The Toyota Yaris gets a new petrol engine

Given the current trend for small-capacity, three-cylinder, turbocharged engines, Toyota’s decision to stick a 1.5 litre, four-cylinder, normally-aspirated petrol unit in the 2017 Yaris supermini might come as a surprise.

A replacement for the long-serving (and very precisely-named) 1.33 litre motor, it’s a member of the ESTEC (Economy with Superior Thermal Efficiency) engine family.

Accordingly, special features include a cooled exhaust gas recirculation system, a water-cooled exhaust manifold and a high 13.5:1 compression ratio. What’s more, electronically-controlled variable inlet valve timing allows a switch between the Otto and Atkinson combustion cycles.

The result is 110 bhp (82 kW / 111 PS) plus 136 Nm (100 lb/ft) of peak torque. Acceleration from rest to 62 mph (100 km/h) takes a fairly respectable 11.0 seconds, which is 0.8 seconds quicker than its 1.33 litre predecessor managed.

Oddly, Toyota hasn’t released any efficiency figures, but a 12 percent reduction in fuel consumption is claimed.

Alfa MiTo TwinAir arrives

Image
The Alfa Romeo MiTo supermini is now available with the innovative two-cylinder TwinAir petrol engine. Although its capacity is only 875 cc, a turbocharger and the MultiAir electro-hydraulic valve control system mean it produces a respectable 83 bhp (62 kW / 85 PS) and 145 Nm (103 lb/ft) of torque. Performance might not be scintillating - the 0-62 mph (100 km/h) sprint takes 12.5 seconds and maximum speed is 108 mph (173 km/h) - but the TwinAir’s trump card is efficiency. Carbon dioxide emissions are only 98 g/km, a level that brings numerous benefits for UK drivers including zero road tax, a full discount on the London Congestion Charge and qualification for the lowest company car benefit-in-kind rate. Fuel economy is also decent and, according to the official figures, a TwinAir-powered MiTo will manage 67.3 mpg (4.2 l/100km) on the combined cycle. Impressive maybe, but still some way off the 78.5 mpg (3.6 l/100km) of the existing 1.3 JTDM-2 diesel MiTo. However, any
