2013 New Verso DPL: More efficient powertrains
- Choice of 5 powertrains: 3 diesel and 2 petrol engines
- Revised 124 DIN hp 2.0 litre D-4D turbodiesel with improved torque delivery, reduced fuel consumption of 4.9 l/100 km and emissions of 129 g/km
- CO2 emissions decreased across the entire engine range, by between 4 and 10 g/km
- Optional towing capacity increase of 200 kg, to 1,500 kg, on 2.0 D-4D versions
The new Verso will be equipped with a choice of five engines, all benefitting from the new frontal design's improved aerodynamic efficiency and the availability of low rolling resistance 17" tyres.
As a result, and with no loss of performance, fuel consumption and CO2 emissions have decreased across the entire engine range, the latter from between 4 and 10 g/km.
The range comprises a substantially revised 124 DIN hp 2.0 litre D-4D diesel, 150 DIN hp and 177 DIN hp versions of a 2.2 litre D-CAT diesel, and a choice of 1.6 litre, 132 DIN hp and 1.8 litre, 147 DIN hp Valvematic petrol engines. All engines also benefit from the wide ranging advanced technologies and internal improvement programmes of Toyota Optimal Drive.
The 2.2 litre 150 DIN hp D-CAT diesel is mated to a 6-speed automatic transmission, the 177 DIN hp variant to a 6-speed manual gearbox. The CO2 emissions of the former have been lowered by 9 g/km to 169 g/km, and those of the latter by 6 g/km to 153 g/km.
Simultaneously, the average fuel consumption of the 150 DIN hp engine has been lowered to 6.4 l/100 km, and that of the 177 DIN hp unit to 5.8 l/100 km.
Both the 1.6 litre and 1.8 litre Valvematic petrol engines are equipped with a 6-speed manual transmission. Both engines' CO2 emissions have been lowered by 4 g/km, to 154 and 158 g/km respectively. The average fuel consumption of the 1.6 litre engine has been reduced to 6.6 l/100 km, and that of the 1.8 litre unit to 6.8 l/100 km.
The 1.8 litre unit may also be equipped with a revised automatic Multidrive transmission which now incorporates a more 'stepped' gear shift feel, with engine revs building in a manner more closely linked to vehicle acceleration.
Revised 2.0 Litre D-4D Diesel Engine
In recognition of the 2.0 litre diesel powertrain's popularity within the C-MPV segment, representing some 47% of the mix, Toyota has extensively revised its 124 DIN hp 2.0 litre D-4D turbodiesel, which complies with Euro 5 emissions regulations and now comes standard with a Diesel Particulate Filter (DPF).
Mated to a 6-speed manual transmission, the unit has been revised to improve torque delivery at low rpm and reduce combustion noise. CO2 emissions have been lowered by 10 g/km to 129 g/km, and fuel consumption has fallen by 0.4 l/100 km to only 4.9 l/100 km.
The unit features a new variable nozzle turbocharger with a lower friction bearing system and an electric actuator, and the torque characteristics of each gear have been adjusted. As a result, maximum torque of 310 Nm is now available 200 rpm earlier and across a wider rev band, from 1,600-2,400 rpm, offering a marked improvement in higher gear throttle response.
CO2 emission-reducing lubrication and cooling circuit improvements include a 2-stage pressure oil pump with improved oil jet, an optimised water pump with a reduced flow rate, and a twin-chamber oil pan to improve engine warming speeds. Exhaust emissions are further lowered through a new glow plug control strategy and improvements to the construction and coating of the DPF.
The use of a resin cylinder head cover, oil cooler bracket and water pipe reduce engine weight by 5 kg. The reduction of friction through the adoption of a low friction vacuum pump, a low friction timing chain and low viscosity oil further enhance fuel efficiency. And combustion improvement through a new piston bowl shape and the new glow strategy has perceptibly lowered engine NVH.Overall, generating higher torque at lower revs, the engine is quieter and torque delivery has become more linear.
As an option, the towing capacity of Verso 2.0 D4D models can be increased by 200 kg, to 1,500 kg.
