Volkswagen T-Roc Hybrid: our test drive of the full-hybrid SUV that arrived a little late

The new version, available in two power variants, joins the 48-volt mild-hybrid models, featuring a technology that has proved successful and which the German group had first introduced a decade ago but subsequently underestimated and then neglected for a long time

The Volkswagen Group’s second full-hybrid powertrain – following the one offered for just a couple of years on a Jetta sold in only a few markets a decade ago – is making its debut in the Golf and T-Roc SUV ranges. Dubbed ‘Hybrid’, these models are the flagship examples of the German group’s strategic shift, but they arrive rather late in the day given the popularity enjoyed so far by full-hybrids from other manufacturers, particularly Toyota and the Hyundai-Kia group, to which models from Chinese brands are now being added. This technological gap has hampered sales of the Volkswagen Group’s brands in high-volume segments such as the compact and mid-size car markets, contributing to the crisis from which it is attempting to emerge through a radical overhaul of its industrial and commercial vision.

Volkswagen T-Roc Hybrid: a three-motor system offering two power outputs

The system – which, as is easily predicted, will be rolled out to other brands within the Volkswagen Group – comprises a 1.5-litre supercharged engine producing 150 cavalli, based on the Miller cycle and featuring a variable-geometry turbocharger, an electric drive unit producing 115 cavalli and another unit acting as both a starter and a power generator. The system does not use a dual-clutch gearbox, such as those found in the Hyundai-Kia group, but a single-speed transmission inspired by that of Toyota’s full hybrids, which allows the electric units and the internal combustion engine to interact via a clutch. In the MQB Evo architecture on which the T-Roc range is based, the positioning of the full-hybrid system’s components slightly alters the weight distribution. In fact, beneath the rear seats, the battery takes the place of the fuel tank, which has been relocated beneath the boot floor.

Depending on driving conditions, speed and the vehicle’s Eco, Comfort or Sport settings, the electronic control system activates the powertrain operating mode it deems most appropriate. Electric mode up to 60 per hour or until power exceeding 20 cavalli is required, with the petrol engine deactivated; the series hybrid operates predominantly in electric drive mode but with the 1.500 petrol engine powering the generator to charge the NCM-chemistry battery, which has a net capacity of 0.64 kWh, to maximise zero-emission driving; and the parallel hybrid, with the petrol engine connected to the front axle and supported by the electric motor’s boost.

The T-Roc Hybrid is available in a version with 136 cavalli and 288 Nm of torque, and another with 170 cavalli and 310 Nm of torque. Both reach a self-limited top speed of 180 all’ora, but the former propels the SUV to 100 per hour in 9.7 seconds with an average fuel consumption of 5.2 l/100 km when the battery is flat, whilst the latter promises acceleration from 0 to 100 in 8.5 seconds and fuel consumption of 5.6 l/100 km.

The Volkswagen T-Roc Hybrid doesn’t stand out much from the rest, but it has a small boot

The Hybrid versions retain the same dimensions as the other T-Roc models, measuring 4.37 metres long, 1.82 metres wide, 1.57 metres high and with a wheelbase of 2.63 metres. Consequently, the interior offers the same generous passenger space, although the large central tunnel at the rear may be a nuisance for the person sitting in the middle; however, the boot is slightly smaller due to the fuel tank being relocated beneath the load floor. In fact, it is smaller than the standard model, with a boot capacity ranging from 340 to 1,212 litres.

Externally, the only difference compared with other T-Roc models is the ‘Hybrid’ badging on the tailgate, whilst inside the cabin, the distinctive features are limited to a redesign of certain interfaces on the 10.3-inch configurable cockpit display and the 12.9-inch central infotainment screen. In practice, the rev counter on the instrument cluster has been replaced by a power consumption gauge, whilst the infotainment system also displays the powertrain’s operating modes and the battery’s charge status.

The infotainment system runs on the Mib4 operating system, features a clear graphical interface offering shortcuts for quick access to certain functions, and includes wireless connectivity for smartphones and a virtual assistant powered by ChatGPT’s AI. Its display sits above the rather impractical touch-sensitive strip used to control the temperature and volume of the hi-fi, whilst the other functions of the three-zone climate control system in the top-of-the-range models are integrated into the central display but remain clearly visible. On the centre console between the seats are the control knob with an OLED screen for managing the hi-fi system, driving modes, the 15-step adjustment of the optional adaptive suspension and the ambient lighting, as well as the smartphone charging pad.

Volkswagen T-Roc Hybrid: it performs well in electric mode, but when it switches to hybrid mode, you really notice the difference

The 170 cavalli Hybrid proves to be very agile, instinctive to drive and consistently reliable, just like the T-Roc mild hybrids, compared to which it weighs only slightly more: 1,514 kg, Naturally, it stands out for the way it handles the roads, making the most of its powertrain’s operating modes. In particular, it lives up to expectations when the electric motor is the sole power source. So, in city traffic – where the efficient automatic regenerative braking quickly recharges the battery – you drive normally on electric power, just as you do on out-of-town roads, provided you don’t demand too much power. In these situations, you travel in silence, relying on linear power delivery. The situation changes when rapid acceleration or a burst of speed is required, on out-of-town stretches and on gradients. In fact, the ‘scooter effect’ typical of single-speed full hybrids becomes apparent when the accelerator is pressed fully, because the internal combustion engine revs up and makes itself felt; by anticipating the actual increase in speed, it delays the linear acceleration promised by the combined output of the 1,500 petrol engine and the electric motor.

During the test drive in the area around Nice, this Hybrid consumed 6.7 litres per 100 kilometres rather than the 5.6 litres claimed by the manufacturer.

Volkswagen T-Roc Hybrid: trim levels and prices

The new version is available in the Life, Style and R-Line trim levels, with prices starting from €36,000 for the less powerful variant and €41,000 for the other, which, however, is only available in the two higher trim levels. The T-Roc Style and R-Line trim levels add to the comprehensive suite of ADAS features for Level 2 semi-autonomous driving – also included in the Life trim – with extras such as heated front seats with a massage function, a keyless entry system and 18-inch alloy wheels.
