In both cars, petrol is the only source of energy.  So improved mpg comes only from running the engine in the most efficient way, and energy recovery while braking.  70 mpg sounds extreme, and certainly not achievable on the North Circular!

I think that the Yaris is a size smaller vehicle than the Jazz so I would expect a better mpg irrespective of the hybrid system. Another factor is that Toyota coupled their hybrid systems with an Atkinson cycle petrol engine which increases the fuel efficiency at the expense of performance. However, more ccs plus a more powerful electric motor than used in the Jazz's IMA system more than offsets the reduced engine performance.

As an aside, Honda used a part Atkinson cycle engine in the Mk 3 Jazz and this is somewhat gutless at the lower end of the rev range but is very economical if driven at a steady 40 mph https://www.theaa.com/about-us/newsroom/fuel-economy-record-attempt. A hybrid would struggle to achieve this mpg under those conditions as the battery adds to the weight but provides little benefit.

The new Honda CR-V hybrid uses a much bigger 2 litre engine running in Atkinson mode, mainly acting as a generator.  Presumably this design philosphy will feed through into a new Jazz hybrid in due course.

Toyotas have a lot more experience of hybrids, i quite liked the automatic hybrid yaris when i tried one but it's noticibly smaller inside than the Jazz.

I found the Yaris too small and dark, the Auris is a bit big, but like the 3 bears, the Corolla might be perfect for my next tuition car.

I am pretty sure with the my hybrid Jazz (2014) you could get 500 miles to a complete tank full (40litres). In my normal Jazz 1.4EX I can get over 100 after the fuel light comes on giving the normal a range of about 400 miles. So far in the Hybrid Jazz I have had close to 500 before I bottled out and refuelled. The fuel light came on at about 400. Another time when I am close to that again and the conditions are suitable and safe I will take petrol with me and run it until it stops and report an example of an absolute range. BTW if you turn off the ECO and put gear shift to S (for second, according to the book) you too can get over 117, but consumption obviously suffers for that period, but it drives like a go kart and is fantastic. Off to Europe again in Jazz for D-Day anniversary.

I regularly get 410 - 450, before the light comes, on in my non-hybrid Jazz.
