- The New Generation Santa Fe offers a choice between two diesel and a petrol powertrain developed by Hyundai Motor for the third generation.
The engines have been modified to meet the new Euro 6C emission standards resulting in an improved fuel efficiency by enhancing the combustion and minimising drivetrain friction losses.
Variable torque control with HTRAC
The Hyundai in-house developed HTRAC is based on four-wheel drive technology that controls variably the power of the wheels. 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 better torque application depending on wheel grip and speed of vehicle.
In combination with the drive modes, HTRAC improves acceleration, stability and fuel efficiency. The system increases traction on snow, gravel and, of course, on regular road surfaces while enhancing cornering performance. The ratio of torque distribution is changed with the drive modes and displayed in the cluster. In sport mode HTRAC delivers improved acceleration with up to 50% torque distributed to the rear wheels. In comfort mode it offers improved stability with up to 35% torque distributed to the rear wheels. In eco mode H-Trac provides improved fuel efficiency by sending power to the front wheels only. In slippery conditions the sytem automatically distributes power to all four wheels automatically.
Enhanced powertrains with new 8-speed automatic transmission
The standard R 2.0 diesel engine has two power outputs: 150 PS (110 kW) and 182 PS (134 kW) and 397 Nm of torque. The engine can be paired with a 6-speed manual transmission (MT) available both with front-wheel drive and four-wheel drive or the newly developed 8-speed automated transmission (AT) with four-wheel drive.
The 2.2-litre CRDi comes with 197 PS (144 kW), 436 Nm of torque and is available with the 6-speed MT or the 8-speed AT and a choice of front-wheel drive and four-wheel drive.
All diesel engines have an improved fuel efficiency by enhancing combustion and minimising drivetrain friction losses. The diesel engines are now also available with an 8AT for an enhanced responsiveness. Handling of the transmission is more direct due to the new control valve and multi-plate torque converter. A double ball bearing minimises friction losses leading to a further improved fuel efficiency. It is combined with a rack-mounted steering (R-MDPS), increasing steering responsiveness and resulting in a higher gear ratio.
The Theta II 2.4-litre petrol engine delivers 185 PS (136 kW), 241 Nm of torque and is available with 6AT and four-wheel drive.
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. The suspension has been stiffened and placed vertically to give a longer travel length for more ride comfort.
The tuned engine line-up ensures softer sound and more linear engine noise with a revised piston design reducing cold noise by 4dB. External vertical shock absorbers optimise responsiveness and stability while improving noise, vibration and harshness levels during driving. Road noise is reduced by reinforcing the floor panel and incorporating more 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.
