Visually the revised i40 features a new front bumper assembly incorporating a prominent hexagonal grille and, for high-spec models, freshly minted LED foglights.
The internals of the i40's headlight unit have also been revised, with the current car's wavy driving lights ditched in favour of a straight line of LEDs.
At the rear, both the sedan and the wagon feature new tail-light graphics. Fresh designs for the i40's 16- and 18-inch alloy wheels round out the list of exterior changes.
Under the bonnet, Hyundai has tweaked the 1.7-litre four-cylinder turbo diesel engine to produce a little more power and torque. The more powerful variant now generates 104kW of power and 340Nm of torque — up 4kW and 20Nm on the current car. Instead of powering the front wheels via a six-speed auto, as is currently the case, this updated motor is paired with a new seven-speed dual-clutch transmission; a six-speed manual is also available in Europe.
To help reduce emissions and improve fuel economy, this engine variant is now fitted with automatic engine stop-start and active front flaps.
The low-power version, which wasn't imported to Australia as part of the pre-facelift range, now produces 85kW/280Nm, up from 85kW/260Nm. This engine is still paired exclusively to a six-speed manual transmission.
No word, yet, on whether the 2.0-litre direct injection petrol engine employed in Australia has been given an upgrade.
New technology available on the facelifted i40 extends to automatic high beam headlights, the ability to read and display speed limit signs, and Advanced Traction Cornering Control, which electronically mimics the behaviour of a limited-slip differential.
The i40 wagon can also be specified with an electronic damping control system, which allows the driver to select between different drive modes that affect the rear suspension settings, steering wheel and throttle response, and transmission shift logic.
Also available on Europe-bound i40s is an updated navigation system with digital radio functionality.
