A CLEVER AND CHARACTERFUL ENGINENo other group of motorists is as loyal to the petrol engine as the A-segment, where it is chosen by 85% of customers. With its comprehensively revised version of Toyota's award-winning 3-cylinder engine, new AYGO provides the ideal balance of response and efficiency that they're looking for.
"We wanted to improve performance, as well as economy," explains Chief Engineer Terai. "In the A-segment, running costs are paramount -customers don't want to spend a fortune on fuel bills. But at the same time, we didn't want to resort to costly technology to reduce consumption, as this would have driven the vehicle price up too much. So our challenge was to come up with relatively simple yet clever ways to achieve our targets."
That explains why the list of improvements to the 998 cc unit is a long one.
First, the combustion character of the engine was improved. The compression ratio has been increased from 11.0:1 to 11.5:1. The combustion chamber now benefits from better cooling, and a high tumble intake port ensures an optimal air/fuel mix in the cylinder. The Variable Valve Timing programme has also been optimised.
Next, friction losses were reduced through the adoption of a low friction timing chain with an auto-tensioner. Diamond-like Carbon (DLC) valve lifters and a twin-tank oil pan further contribute to reduced internal resistance.
And finally, what was already one of the lightest engines of its type was made even lighter by fitting a cylinder head with a built-in exhaust manifold.
The engine now develops greater power and torque — 51kW (69 DIN hp) at 6,000 rpm and 95 Nm at 4,300 rpm. 85 Nm of torque is available from as little as 2,000 rpm.
New AYGO comes in both standard and Eco-versions. The latter benefits from a longer 4th and 5th gear, low Rolling Resistance Coefficient.
The standard version achieves a drop in fuel consumption from 4.4 to 4.1 l/100km , which translates into a 7 g/km* drop in CO2 emissions to just 95g/km*. The Eco unit does even better, with fuel economy of below 3.9 l/100 km* and CO2 emissions of 88 g/km*.
Through all of these improvements, close attention was paid to maintaining the engine's sprightly character. It will still rev happily to high speeds and, though sound insulation has been improved, its sporty sound-signature is still there when pushed hard.
Finally, extensive work was done on the aerodynamics of the car, to further enhance efficiency. This includes the optimisation of airflow around the bodywork to reduce air resistance, the use of front and rear spoilers, floor undercovers and rear spats to control the underfloor airflow, and the adoption of a four-way duct to optimise airflow to the engine bay.
As a result, the drag coefficient of new AYGO has been reduced from Cd 0.30 to Cd 0.29, with a further reduction to Cd 0.28 for the Eco variant.
X-SHIFTThe x-shift transmission is available as an option on new AYGO. This vastly improved automated manual transmission has a fully automatic shift mode and no clutch pedal, using computer control to synchronize engine, clutch and transaxle for quick and precise shifting.
The transmission's gear ratios have been revised for a better balance of driving pleasure and fuel economy.
Selecting E (Easy Mode), M (Manual) or R (Reverse) allows the car to 'creep' like a conventional automatic. In E mode, the system selects a suitable gear according to the accelerator pedal, vehicle speed and driving conditions. New AYGO's x-shift is equipped with the kick-down function standard to automatic transmissions. Moreover, it is possible to override the system temporarily by using the steering wheel-mounted paddles.
Selecting M mode allows the driver to manually change gear via either the shift lever itself or with the paddle switches.
When equipped with x-shift, new AYGO returns fuel consumption of 4.2 l/100 km* and generates CO2 emissions of only 97 g/km*.
