Hyundai Santa Fe – the new technologies and The hybrid engines in the facelift

Less than a month ago we unveiled the first details related to the restyling of the Hyundai Santa Fe. We now have the ability to also share other updates relating to the fourth generation of the Suv Korean, launched in 2018. News relating to, this time, technical details, the new platform and, especially, the new hybrid engines (full and plug-in) that will be part of the new range, the launch of which is expected in October.

Change the platform. The new Santa Fe, which we had already told the cosmetic changes and those relating to the interior, is the first of Hyundai’s european built on the platform of the third generation, already used on the Sonata. An architecture that enables advantages in terms of performance, handling, efficiency and safety. Great attention has been paid to the positioning of the groups of “heavy”, also related to the hybrid, in the lower part of the platform, so as to improve the center of gravity and the behavior of the road. In this regard, revised the attachment points of the steering arms, with the aim of improving the handling. The new architecture, in addition to guaranteeing a soundproofing more organized compared to the current series, it still offers more ease to the occupants, despite the presence of the powertrain electrified. This is confirmed by the dimensions: length, 4.785 mm (+15 mm), width 1.900 (+10 mm), height 1.685 (+5 mm), while the pitch remains unchanged (2.765 mm). The positioning of the battery pack under the passenger seat in the full edition, hybrid, and under the front seats on the variant of the plug-in does not results in reductions of space in the passenger compartment or in the trunk. Indeed, the Suv offers three inches more for the legs of those seated in the second row, and four more for those who are in the third row (this last option, however, has not yet been confirmed for the uk).

Full and plug-in hybrid. Two arrivals of leading in the engine range: the full hybrid and the plug-in. The first, available at launch, is constituted by the combination of the new 1.6 T-GDi turbo petrol direct injection and an electric motor 60 HP (total power of around 230 HP, not yet formalised), which is powered by a rechargeable lithium-ion battery from 1.49 kWh. Full hybrid that will be available in versions with two or four wheel drive. The plug-in hybrid, however, which will come at the beginning of 2021, it will be offered with the same 1.6 T-GDi, combined, however, an electric unit 91 HP (total power, 265 HP) and a lithium-ion battery to 13.8 kWh. This variant will be available with all-wheel drive. Both the powertrain hybrids will also be matched to an automatic transmission six-speed gearbox of new design. The engine 1.6 T-GDi, then, is the first to use the technology Cvvd (Continuously variable valve duration), which regulates the duration of the opening and closing of the valves according to driving conditions, providing an increase in performance and improvements in efficiency and, consequently, in emissions. This is also the system of recirculation of the exhaust gas at a low pressure (Lp-Egr), to further optimize the efficiency. Alternatively, the range will also offer the 2.2 turbodiesel up to date to get power consumption and performance more brilliant. Compared to the previous generation, the engine block is now aluminum, with a weight savings of 19.5 kg. Different parts of the four-cylinder has been revised, as for example the camshaft. Furthermore, it has been adopted a new system of fuel injection that works to 2.200 bar (was at 2000), with the aim of increasing the performance. The diesel version, which delivers 202 HP and 440 Nm of torque, is available in front-wheel drive or. And could be matched – but the House has yet to confirm – a new automatic gearbox eight-speed “wet” dual-clutch in oil bath.

Wheel drive 4×4: now there is the knob. As in the previous series, the Santa Fe is equipped with all-wheel drive system Htrac, the combination of the words “Hyundai” and “traction”. For the first time, however, the Suv the Korean use the selector Terrain Mode: a knob located on the tunnel that allows you to select the mode and dynamics settings related to traction, suitable to various types of fund (such as sand, snow and mud, while those related to driving are eco, sport and comfort). In addition, the smart driving mode, involves the automatic recognition of the driving style on the part of the car, which will select the setting most suitable, without which the driver should do. In poor grip conditions, power is automatically distributed to the four wheels. In sport mode, however, the system Htrac points to the performance, by sharing up to 50% of torque to the rear wheels, while in comfort you can distribute up to 35% on the rear axle. By activating the eco function, finally, the system aims to save fuel, using only the front-wheel-drive.

Security: the package more rich. The Santa Fe is equipped with the safety package active Hyundai SmartSense further enhanced. For the first time, in fact, the Suv is equipped with the Highway driving assist (Hda): the function can be activated from the steering wheel, it is a combination of the Lane following assist and Smart cruise control, which uses sensors and navigation data to automatically adjust the speed. Another new feature, the Reverse-parking collision avoidance assist (Pca), using the camera and the rear sensors detect obstacles when reversing, providing an alert and applying the brakes, if necessary, to avoid a collision. The Remote smart parking assist (check out our latest video), you can move forward or backward in the car using the key, without being on board. Other systems are the Forward collision avoidance assist (Fca), the Blind spot collision warning (Bcw), the Blind spot collision avoidance assist (Bca), the Safe exit assist (Sea), the Blind spot view monitor (Bvm), the Lane following assist (Lfa) and the Rear cross traffic collision avoidance assist (Rcca).
