What would be interesting is to look at the average fuel consumption of the 1960 car and compare it with the average fuel consumption of the 2017 car and then also compare with a 2017 car that was the same dimensions, weight and power of the 1960 car
So this is completely just my experience.
I've fairly consistently owned Similar size cars throughout my life so let's run through it.
1985 Sigma.2.6l cab manual Manual this guzzled fuel.. 15l/100 urban was typical.
1992 pulsar 2.0 fuel injected manual 10-12 urban.
2002 Mini Cooper 1.6 Supercharged manual. 10/11 urban
2004 Fiesta 1.6 man. 8/9 urban
2008 Audi 1.8 turbo DSG Direct injection, 8 urban
2016 VW 1.4 turbo DSG Direct Injection 6/7 urban.
All of those cars are broadly similar (except the sigma LOL). I'm constantly gobsmacked by the fuel efficiency of the current VW. That's a massive drop in consumption over the years. It's got all the current fuel saving tech. Stop/start, electric power steering (and AC I think), small capacity turbo. On the highway I can get mid 4's which is circa 60 MPG in the old money. Not that I've ever done a long highway trip, but 1000k off a 50 litre tank is plausible.
Clearly.. going forward I think that ilk of car will be viewed as "the end of the line" for ICE efficiency. The only way forward from here is increasing electrification. I think when we (if) actually force manufacturers to comply with current and future emissions regs the cars will cease to become more economical. Also, some other technologies that were mooted for ICE I don't think will ever see the light of day due to it just being simpler to electrify.
It's at this point that I'd like to mention...
