Jaguar I-Pace

So in the future when guys are in the Pub comparing their EVs it will be a case of

..... mine is smaller than yours !

Watts per mile that is.

I guess when pretty much every car on the road has a sub 4 sec 0-60 time, alternative "performance" metrics will be required. Battling through the morning traffic today I was pondering the effect of everyone having supercar performance off the line and I don't think it will be good!

I guess its all relative but lets hope the brakes and reactions are up to job!

We will all be chauffeured by the cars' computers with top notch reactions.

Until that computer displays the message ‘fatal error’!

See that (FWIW!) AutoExpress have just done an I-Pace vs Tesla S 75D comparison. One figure for the I-Pace that caught my eye - simply because I've looked for it but not seen it quoted before - was the 30-70 time at 3.7 sec. I know that's pretty quick and certainly quicker than my Macan SD, but - genuine question - don't know how it compares to other Macans, eg GTS or Turbo. Anyone able to point me at some Macan 30-70 review figures please? (The Tesla was 3.5 secs for comparison.)

(Yes, I know it's just one performance metric but I'm probably more interested in 30-70 as an indication of overtaking performance than any other single stat - it's just more relevant to everyday driving on single carriageway roads than eg 0-60.)

The petrol S has been tested from 30 > 70 in 4.3 sec

This link compares the Macan Turbo to the M3.

Interesting read. It also compares the 30-70mph times. But I feel it’s faster than 4.2seconds as mentioned.

What you notice most in daily driving is the instant pickup. No waiting for downshifts and drivetrain inertia. It's worth at least another second on top of the actual time it takes to cover the interval. It makes overtaking even more effortless as you are always instantly ready to go.

To put this in perspective the Model S P100D has been timed at 2.19 sec from 30-70 mph! Obviously a huge price premium, but that is the current EV benchmark.

0-60 30 -70 times are all well and good, but the elephant in the room is still range, especially at motorway speed of 70-80.

As more EV's hit the road, demand for charging points will increase, probably more so than availability, so I am thinking surely working on some form of gearing to extend the range, albeit at the expense of acceleration, should surely be on the to do list of EV manufacturers.

An 'elephant in the room' is something that's patently obvious but which people refrain from talking about. Not sure how that applies to EV range. Most everyone who buys an EV understands the range issue. The answer seems to be that provided you can charge at home and don't do more than 12-15K miles/year then range is not a serious concern for most users, though long journeys do need to be planned more carefully. Most EV drivers seem content with this trade-off.

As more EV's hit the road, demand for charging points will increase, probably more so than availability

Not sure why that should be the case. There may be something of a lag between demand and supply and the picture probably isn't going to become clearer until eg 2020, but my guess is that the DoT will progressively play a stronger role in ensuring the build-out of rapid chargers to meet demand, as part of the overall strategy to electrify transport.

, so I am thinking surely working on some form of gearing to extend the range, albeit at the expense of acceleration, should surely be on the to do list of EV manufacturers.

Would mechanical gearing really help? If a certain power delivery is necessary to sustain the momentum of a car at eg 80mph then why would that reduce by adding the extra inefficiency of mechanical gears. I'm not sure how much of a part acceleration plays in overall consumption, but if it's significant then couldn't it be controlled more easily by electronic rather than mechanical means.
