Review: Kia UM.I Sorento (2015-17)

Overview

Released in Australia in June 2015, the Kia UM Series I (UM.I) Sorento was a seven-seat SUV. Manufactured in South Korea, the UM Sorento was available with two powertrains:

Front wheel drive and with 3.3-litre V6 petrol engines; or,
All-wheel drive and with 2.2-litre four-cylinder turbo-diesel engines.

For both engines, a six-speed automatic transmission was fitted as standard.

The Kia UM Sorento range initially consisted of Si, SLi and Platinum variants. In October 2016, however, range-topping GT-Line variants were introduced.

D4HB diesel and G6DB petrol engines

Of the engines,

the 2.2-litre D4HB ‘R’ diesel engine had an aluminium engine block and cylinder head, common-rail direct injection with piezo injectors (operating at 1800 bar), a variable geometry turbocharger, double overhead camshafts, four valves per cylinder and a compression ratio of 16.0:1; and,
the 3.3-litre G6DF ‘Lambda’ V6 petrol engine had an aluminium block and cylinder heads, multi-point injection, double overhead camshafts, four valves per cylinder, dual continuously variable intake valve timing (D-CVVT), a variable intake system (VIS) and a compression ratio of 10.6:1.

For both petrol and diesel models, the driver could select from Normal, Eco and Sport drive modes which varied gearshift behaviour and steering assistance.

Over the combined ADR 81/02 test cycle, fuel consumption for the petrol and diesel engines was 9.9 litres per 100 km and 7.8 litres per 100 km, respectively.

All-wheel drive system

Like the Kia SL Sportage , the UM Sorento models with 2.2-litre turbo-diesel engines had a ‘Dynamax’ all-wheel drive (AWD) system that was manufactured by Magna International . In normal conditions, the engine’s torque was directed to the Sportage’s front wheels. The Dynamax AWD system, however, was pro-active in that it used inputs from sensors to monitor driving conditions and anticipate AWD requirements, rather than responding to a loss of traction (reactive). When a loss of traction was anticipated, the electrohydraulic multi-plate clutch would engage to direct up to 50 per cent of the engine’s torque to the rear axle.

For the Kia UM Sportage, the Dynamax AWD system included a ‘4WD Lock’ mode provided a 50:50 front:rear torque split for low-traction conditions. Furthermore, an Advanced Traction Cornering Control (ATCC) function could:

transfer torque to the wheels with the most grip; and,
reduced understeer by braking the inner rear wheel and providing more torque to the outer rear wheel.

Body and dimensions

Compared to the Kia XM Sorento , the UM Sorento was 95 mm longer (at 4780 mm), 5 mm wider (1890 mm), 10 mm lower (1690 mm) and had an 80 mm longer wheelbase (2780 mm); ground clearance was 185 mm. Kerb weight for the petrol and diesel Sorento models was 1875 kg and 1985 kg, respectively.

The UM Sorento’s bodyshell consisted of 52.7 per cent ultra-high tensile steel (UHTS) and, relative to its XM predecessor, achieved a 14 per cent increase in torsional rigidity. For greater refinement, other developments included:

new soundproofing material for the transmission tunnel;
a thicker dashboard soundproofing panel (increased from 0.7 mm to 0.9 mm);
larger engine and transmission mounts; and,
for diesel models, a new diesel particulate filter (DPF) cover and an acoustic shield integrated into the engine’s timing chain cover.

The Kia UM Sorento had maximum braked towing capacity of 2000 kg.

Suspension

The Kia UM Sorento had MacPherson strut front suspension and independent, multi-link rear suspension. For the UM Sorento, changes include larger shock absorbers mounted vertically behind the axle line for improved body control and larger bushings for the rear subframe. Furthermore, Australian-delivered Sorento models had suspension settings developed specifically for local conditions.

Steering

The Kia UM Sorento had a rack-mounted, electric motor-driven power steering system (Kia’s R-MDPS). The turning circle for the Kia Sorento was 11.1 metres.

Safety equipment

Standard safety equipment for the Kia UM Sorento included dual front airbags, front side airbags, curtain airbags (for the front and second row occupants), ABS, electronic brake force distribution, brake assist, electronic stability control, traction control, active front seat head restraints and front seatbelts with pretensioners and load limiters.

The Sorento Platinum and GT-Line were further equipped with:

Lane Departure Warning System (LDWS): used a forward-facing camera to detect the car’s position within its lane and alerted the driver if they departed from the lane without indicating;
Blind Spot Detection (BSD) and Lane Change Assist (LCA): monitored the area up to 70 metres behind the Sorento and provided a visual warning in the door mirror when another car enters the driver’s blind spot;
Rear Cross Traffic Alert (RCTA): could detect approaching traffic that may cross the vehicle’s intended path when reversing out of a parking space and warn the driver; and,
Smart Cruise Control (SCC): could maintain a pre-set distance between the Sorento and the vehicle ahead, accelerate back to the pre-set cruising speed when the road ahead was clear and bring the vehicle to rest in congested traffic.

From October 2016, the Kia Sorento Platinum and GT-Line were equipped with Autonomous Emergency Braking (AEB) which used front radar sensors to monitor the distance to objects ahead. If the distance decreased such that there was a risk of collision, a warning tone would sound to alert the driver. If a collision was imminent, the brakes would be applied to reduce vehicle speed and the severity of the impact.

Brakes

The Kia UM Sorento had 320 mm by 28 mm ventilated front brake discs and 305 mm by 11 mm solid rear discs.

Euro NCAP and ANCAP assessments

In Euro NCAP testing , the Kia UM Sorento – fitted with a 2.2-litre turbo-diesel engine – received a five star safety rating which included a 90 per cent adult occupant protection rating and an 83 per cent child occupant protection rating. In the offset crash test, protection of the driver’s head, neck, thighs and feet were rated as good, though chest protection and lower leg protection were rated as adequate (i.e. a slight risk of serious injury. In the side impact and pole tests, occupant protection was rated as good for all areas.

Under ANCAP’s 2015 methodology , this testing resulted in five star adult occupant protection rating with a score of 36.62 out of 37.

The limited-run Kia Sorento Si Limited was released in May 2017. Available with petrol and diesel engines, the Sorento Si Limited had the same retail price as the Si variant on which it was based, but added 18-inch machined finish alloy wheels, leather-appointed seats and a premium steering wheel with wood-look trim. The Kia Sorento Si Limited was available in four paint finishes – Clear White, Aurora Black, Silky Silver and Snow White Pearl – and could be identified by its ‘Limited’ badging.
