Even Honda have gone for a wet belt set up in one of their engines ffs.

Well, if you are correct, then it wont be long until we see a string of broken down Shark PHEV along the side of the road. Hey?

And if we don't?

Perhaps the way people use the Shark 6 will determine if there’s issues or not,
anything at the moment is pure speculation but sounds like plenty of “guinea pigs”
are prepared to be early adopters….

I suspect this is gonna be a repeat of diesel Focus.
Marketing and sales sold cars to people to be used in the wrong application, resulting in a lot of burned and unhappy customers.
Going off the carsales fuel figures we will probably see a lot of unsatisfied buyers who are spending more on fuel than Ram and Silverado owners.
Time will tell, maybe we revisit this in a year and see.

It will most likely average low 5l/100km.
It’s burning three times that pushing this thing down the road at highway speeds when the battery reserve is depleted. That is a huge increase in the amount of work that engine has to do.


For reference. I’ve had both 100 series petrol V8 and turbo diesel.
Towing the same weight approx 2.2 tonne diesel in the vicinity of 14l/100km, petrol V8 20l/100km.

Fiesta ST I use as my daily, 1.6L turbo 4 ~250,000km on the clock and its hauling me around + a boot full of tools, does a bit of farm track work and off road access to infrastructure.

6.3L/100km on average but does 7-8L/100km if I do a lot of suburban traffic.

Somewhat interestingly, its capable of matching or bettering fuel economy its naturally aspirated brother in my shitbox fleet, both 1.6L 4 cylinder engines, same driver, same tools, same routes.

Somewhat curious to see what the BYD Shark does in suburban trade type work where you're doing traffic light to traffic light with some tools, or say 1.7 tonne excavator on machinery trailer, you'd probably be able to comfortably do that with 2500kg towing capacity.

So if a vehicle gets 8 litres/100 km on the highway then expect around 24 litres/100 km when heavy towing.
It’s not perfect but seems to work for a lot of full sized gasoline pickups in the US but turbo petrol can be even worse.

Diesel engines seem to give about 30% better fuel economy when towing compared to petrol engines..

Hope this helps with estimations…

I think these days with a lot of the modern high torque engines, it's closer to double than triple.

Not according to lots of American tests, even BEVs use up to triple the energy when doing a heavy tow,
It’s not uncommon for full size gasoline Utes to go from US22mpg down to 7 mpg when doing max towing.
Also, the usable range is roughly a third of max distance on the battery. F150 can get by with us36 gallon tank
but the Lightning is stuck with an impossible task of recharging on anything longer than 160 km trip.
