Toyota builds a hydrogen-fuelled GR Yaris

To demonstrate how traditional internal combustion engines could use hydrogen instead of petrol, Toyota has created the GR Yaris H2 concept.

This one-off car features the same 1.6-litre, three-cylinder, turbocharged unit that powers the regular GR Yaris, albeit with modified fuel-supply and injection systems. Its hydrogen tank and associated ancillaries are taken from the current Mirai fuel cell electric vehicle.

Hydrogen is supposed to offer good responsiveness (due to a fast burn rate) and reduced emissions. However, objectively assessing the GR Yaris H2 is pretty much impossible, because Toyota hasn’t released any output, performance or efficiency data.

Furthermore, the company’s experimental hydrogen-combustion technology isn’t ready to go into production yet, but development work is ongoing. Any future market launches are likely to depend on whether or not an adequate hydrogen infrastructure is in place.

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
