Hi Philip,

Yes you’re right — the T8’s acceleration is a combination of the engine and the electric motor working in concert. When you run the battery down in electric-only mode, it will always keep a minimal charge on board, so that the car can then function in hybrid mode. If you use maximum acceleration repeatedly and in quick succession, you might well reach a point where the battery cries enough, but it will have charged up again — from both the engine and the regenerative braking system — to go again within a few minutes. 

Wall chargers generally cost around €900 to €1,000 fully installed, but there’s a grant from the Sustainable Energy Authority Ireland available that will cover up to €600 of that.

Finally, you’re absolutely right — a V60 only gives away a 31-litre advantage to the larger V90 when it comes to boot space.

Hi Andrew,

That’s a tricky one as you’ve not told us the precise cars in question. The thing is, an electric car with a price of €30,000 has probably already had the VRT rebated on it, so you won’t make as big a saving — you’ll only save the VAT, which will represent a discount of around €5,000, bringing the price down to around €25,000. 

With the hybrid, assuming it has CO₂ emissions of under 100g/km, and therefore is in the 15 per cent VRT band, you could make a huge saving. It’s a rough guess, but we reckon you’d save €4,000 worth of VAT and €3,000 worth of VRT, bringing the price down to €17,000. 

Now, these are just rough calculations, and the final, proper figures may differ, but on the face of it the hybrid model offers a better up-front saving, but then you have to work in the potential for much cheaper running costs with an electric car when it comes to fuel and servicing.

Hi Robert,

The M50d has more peak power and torque and is quicker accelerating than the hybrid model, no question. However, the six-cylinder diesel engine is a lot louder and less smooth than the straight-six in the xDrive45e model and obviously, when the hybrid is running in electric mode it is far far quieter again. As you say, the PHEV comes with compromises, and may not be as economical over a long journey where the battery cannot be charged from an external source.

Hi Harry,

The most likely culprit is that there’s some electrical item draining the system as you’re driving. Or, possibly if you’re only driving for short hops, the engine is still in its warm-up phase and can’t be shut down by the stop/start. Or, and this is a wild guess, Land Rovers often have flakey electrics. 

Maybe read our Why won't my car's stop-start system work? feature for further understanding. We get a lot of questions like this.

Hi Tom,

It’s lovely — plenty powerful enough, decent economy and good refinement. Arguably, the hybrid is the better Auris model, but if part-electric power’s not your thing then the 1.2 is a very good substitute.

Hi Robert.

Stop-start systems have a mind of their own — literally. They’re designed to only stop the engine when demand for electrical supply within the car falls low enough that it’s safe to do so. So if you’re running the air conditioning, for instance, or have the heat turned up, or if the engine is still in its warm-up phase, then it will either not shut the engine off at all, or will only shut it off briefly. Driving style also plays into it, as does where and when you’re driving. It also depends on the battery condition, so if you’re concerned about the short stop-start times, it’s worth having the health and charge level of the battery checked.

Finally, as we get so many questions on this subject, we put together a quick feature on it for your interest: Why won't my car's stop-start system work?

Hi Neil,

Bikes are taxed according to their engine capaciity. The current rates go like this: €49 for 0-75cc; €67 for 76-200cc; and €88 for 201-9,999cc. I really want to find the person who’s taxing a 9,999cc bike… Electric bikes are taxed on a flat rate of €35 a year.

Hi Mat,

The Tarraco XCellence Lux isn’t actually officially offered in Ireland, but it is available in the UK. It’s basically an XCellence with 20-inch wheels, leather sports seats, electric seat adjustment, ’top view’ parking camera and a winter pack with heated front and rear seats and headlamp washers.

Hi Michael,

It depends on the vehicle, and what Revenue reckons the Open Market Selling Price in Ireland is. There’s a €5,000 VRT rebate on any electric car when you import it so unless the car is so expensive that it incurs VRT of more than €5,000 you won’t pay a penny.

Hi Mike,

Anything is possible, though you might find the effort outweighs the gain. Best bet is to employ the services of a good auto-electrician to assist you with this.
