Hunter REEV tech and its Chinese double cab rivals
Like all Chinese car companies trading in South Africa, Changan know the value of double cab bakkies for profitability. But what are the benefits and disadvantages of Hunter REEV and its advanced design? And who are the rivals?
Changan’s Hunter REEV double cab bakkie is powered by an advanced powertrain, where the petrol engine only supports battery charge.
You can fuel up and plug-in both elements of the powertrain, making range-anxiety and heavy fuel consumption (a weakness of non-plug-in hybrid bakkies) irrelevant. But does the tech all make sense? And how does it compare to other double cabs in the local market, with hybridised powertrains that combine petrol power with batteries?
A turbopetrol generator?
Changan’s Hunter REEV has a notably different powertrain from what most South African bakkie buyers are used to. It’s not a diesel (obviously). And it’s not a PHEV or HEV, either. It’s a REV, where the turbopetrol engine never drives the wheels, but only charges the battery. That means this is a true battery electric drive bakkie, with petrol power functioning as an on-board generator.
Some engineers believe this is the best way to do a blended powertrain with internal-combustion power and batteries. Why? Because the petrol engine is never straining at very high rpm. It’s always running at its most efficient rpm, because it functions solely as a constant output power generator for the battery pack, which is doing the actual driving. And there’s no argument that pure electric drive is smoother and more responsive, in daily driving conditions, than a petrol or diesel.
Hunter REEV’s power generator is a 2-litre turbopetrol. This engine is rated at 140 kW of maximum power, but it’s configured to run at 100 kW of output. Why? That’s the sweet spot between efficiency, durability, and keeping the Hunter REEV’s battery pack charged – and long-term petrol engine maintenance low. If it only acts as a generator, should it be turbocharged if long-term powertrain durability is one of the Hunter REEV’s supposed benefits? That’s a fair question…
Two electric motors power the bakkie’s actual driving. There’s a 70 kW/150 Nm one on the front axle and 130kW/200Nm at the rear. That makes 200 kW and 470 Nm of combined output, which is plenty powerful. Changan claims 0-100 kph in 7.9 seconds, and despite the Hunter REEV weighing 2360 kg, that’s an entirely believable number. Making it faster than most turbodiesel double cab bakkies.
How far can it go – how much can it carry?
The clever bit is that Hunter REEV has a lot of on-board energy, in the form of petrol and battery capacity. There’s a 70-litre fuel tank and 31.18 kWh lithium ion phosphate battery, which can be recharged.
Range numbers are impressive. You can cruise 180 km on pure battery power, if it’s fully charged. And with a full 70-litre tank of fuel and charged battery pack, the Hunter REEV can theoretically run for 1000km.
The core bakkie utility numbers aren’t amazing. Loadbed capacity is very modest, at only 495kg. And the towing ability is a third less than Ranger or Hilux double cabs, which can haul a braked 3500 kg trailer, whereas the Hunter REEV is only rated for 2200 kg.
Hunter REEV’s loadbed does feature a potent 3.3 kW power outlet, with 220v, which can keep your camp lighting or any power tools going for hours (or days), if you need to.
More ‘all terrain’ than off roader
Hunter REEV’s all-terrain ability is limited by the form factor and packaging of those electric motors at each axle. It has 220mm of ground clearance, which is average but adequate. The tyres are 265/60/18s, which should provide a reasonably comfortable ride quality on potholed backroads and corrugated dirt surfaces.
It’s more of an all-terrain bakkie than a dune conqueror or rock crawler. There’s no transfer range or mechanical axle lockers. Changan has given Hunter REEV a centre diff lock, and then it uses the electric drive control at the front and rear motors to split countering-torque when there’s wheel slip. It’s handy, but no substitute for low-range gearing or true axle lockers in really challenging off-road terrain.
Like most double cab bakkies, the Hunter REEV has independent front suspension to ensure it has decent steering authority.
At the rear, instead of a leaf-sprung solid axle, like most other double cabs on sale in South Africa, the REEV uses a different design. It has a five-link semi-independent rear suspension set-up, complete with coil springs, like what you’d get on a bakkie-based SUV like Fortuner or Everest. In theory, that should give the REEV good small bump absorption ability, enhanced ride comfort and superior stability on corrugated dirt roads. Coil springs are better at smoothing out surface corrugations and bumps than leaf-sprung axles.
The disadvantage is that when fully loaded, a bakkie with a coil-sprung rear axle tends to sag more at the rear than a leaf-sprung version.
Hunter REEV rival – GWM P500 HEV
Big, luxurious, and powerful. The P500 HEV demonstrates GWM’s capabilities, although its sheer size and heavy fuel consumption make it a difficult sell compared to traditional turbodiesel double cabs.
P500 HEV’s advanced powertrain has excellent overtaking acceleration at highway speeds. And it’s whisper-quiet and smooth at slow speeds, around town. This is a very relaxing double cab to be crawling along in during peak hour traffic.
Can tow a proper 3.5t (braked), but payload is low at only 735 kg. P500 HEV has a proper low-range transfer case and (electronic) axle lockers, making it reasonably capable off road in steep terrain, although the 224mm ground clearance isn’t amazing.
An issue is its sheer size. Double cab bakkies are too big for most parking areas and covered parking garages. And P500 HEV is a touch larger than Ranger or Hilux, making it even more of an anxiety to park and drive around tight parking garage infrastructure.
The powertrain is wonderfully advanced, but without plug-in recharging, the P500’s hybrid system is just too heavy on fuel, with real-world consumption going to 13l/100km and worse.
BYD Shark 6
Arguably the most advanced double cab on sale in South Africa, from the world’s biggest manufacturer of battery-powered vehicles.
Brilliantly integrated plug-in hybrid power and drivetrain make it incredibly versatile. Like Changan’s Hunter REEV, the Shark 6’s turbopetrol engine primarily functions as a generator for the 29.6 kWh battery pack.
Electric only range is 85 km. With the full battery capacity and a 60-litre fuel tank, you should be good for 760 km of range. Plug-in recharging from a mid-power DC charger gets you 50% battery capacity in only 20min. True to BYD’s reputation as the global leader in all things EV and PHEV, the Shark 6 is very easy to live with regarding recharging.
With 321kW of peak system output, overtaking acceleration is terrific. It’s heavy, though, and without a low-range transfer case Shark 6 has limited off road ability in steep, technical terrain, despite 230mm of ground clearance and all that power.
Not a hauling hero, either, with only a 2.5t maximum braked tow rating. Payload isn’t terrible at 835kg, but that is still more than 100kg less than traditional turbodiesel double cabs.
