The all-new Hyundai Santa Fe: Driving performance

The all-new Santa Fe is equipped with the 2.2 CRDi ‘R’ diesel engine, upgraded with the addition of both selective catalytic reduction (SCR) and lean NOx trap (LNT) technologies to further reduce emissions in conjunction with the diesel particulate filter (DPF) system. These modifications meet the new Euro 6d-TEMP emission standards resulting in improved fuel efficiency and decreased emissions.

Variable torque control with the new HTRAC technology

Hyundai’s newly developed HTRAC system is based on four-wheel drive technology that controls the power of the wheels variably. The name is a combination of the ‘H’ from Hyundai and the first part of the word ‘traction’. The HTRAC variable torque control enables agile handling and enhanced torque application depending on wheel grip and vehicle speed.

In combination with the drive modes, HTRAC improves acceleration, stability and fuel efficiency. The system increases traction on snow, gravel and on regular road surfaces while enhancing cornering performance. The ratio of torque distribution, which can be changed with the three new drive modes, is displayed in the cluster. In Sport mode, HTRAC delivers improved acceleration with up to 50 per cent torque distributed to the rear wheels. In Comfort mode, it offers improved stability with up to 35 per cent torque distributed to the rear wheels. In Eco mode, HTRAC provides improved fuel efficiency by sending between 80 per cent and 100 per cent of torque to the front wheels. In slippery conditions the system automatically distributes power to all four wheels, for optimum stability.

Enhanced powertrains with new 8-speed automatic transmission

The standard 2.2-litre diesel engine produces 200 PS (147.1 kW) and 440 Nm of torque. The engine can be paired with a 6-speed manual transmission (6MT) or alternatively with the newly developed 8-speed automatic transmission (8AT), and is available with either front-wheel drive or four-wheel drive. Average fuel consumption for the 6MT front-wheel drive car is up to 49.6 mpg, with CO2 emissions from 150 g/km; while the 6MT four-wheel drive car offers 47.1 mpg with CO2 emissions from 158 g/km. The 8AT front-wheel drive model returns up to 48.7 mpg average, with CO2 emissions from 153 g/km; and the 8AT four-wheel drive car offers a combined 45.6 mpg, with CO2 emissions from 162 g/km*.

The 2.2-litre diesel engine has improved fuel efficiency due to enhancing combustion and minimising drivetrain friction losses. The Santa Fe’s powertrain line-up will be further expanded in the future with the addition of two newly developed, efficient alternative powertrains: a hybrid and a plug-in hybrid version.

The newly developed 8AT is engineered with a transverse layout, providing a more compact set-up and an increased gear span for enhanced performance and reduced fuel consumption. The gear ratio is widened by 18.3 per cent resulting in an improved engine response during initial acceleration. During braking, the engine response is also improved due to a higher downshifting point. The higher gear ratio width ensures greater differentiation of the drive modes.

The rack-mounted steering (R-MDPS) is a first for the Santa Fe and is combined with the 8AT. R-MDPS means that the electric motor module is attached directly to the steering rack, ensuring high steering stability at high speeds as well as improved precision and quick steering response at low speeds. The steering gear ratio is increased to 60 mm/rev for an overall higher steering response. The new R-MDPS is also lighter than the previous system.

Ride and handling

The development strategy for the fourth generation Santa Fe’s suspension and steering was to improve responsiveness and vehicle stability while also enhancing comfort and overall quietness.

The suspension delivers a smoother ride feeling by reducing the impact and vibration when driving on rough roads. It has been stiffened, but now gives a longer travel length for greater ride comfort.

The revised diesel engine ensures a quieter and more linear engine noise with an optimised piston design that reduces cold noise by 4dB. External vertical shock absorbers optimise responsiveness and stability while reducing noise, vibration and harshness during driving. Road noise is also reduced by reinforcing the floor panel and incorporating higher grade materials in the carpet.

The optional self-leveliser controls the continuous ride height regardless of the vehicle loading by a self-contained damping and levelling control.
