You have to remember, it's the mileage vs the power output. The smaller turbo engines are getting much better mileage but they are making way more power. This is why Honda can stick a 190hp 1.5l turbo motor in a CRV. It has great performance and the economy is not suffering. Honda sticks in tiny non turbo motors in their home market because they need economy. In the US, we want something big and it needs to scoot down the road.I think my post has been misinterpreted slightly. My main objection to turbos is not that they are a hight maintenance item. Modern day turbos do hold up well. My main point is that they are a performance thing and do not usually help with economy. Manufacturers claim that by using a turbo they can go with a smaller engine in order to get better gas mileage. If you compare specs of the smaller turbo engines, they don't get any better mileage than the earlier non-turbo engines.
And if I remember correctly, the Elio is primarily promoted as an economy vehicle.
If Elio was going after economy, then they would literally choose a VW TDI motor that blows the doors off of any gasser motor when it comes to mileage. If the existing Elio motor can give 84 mpg, the VW TDI would hit 100. Plus Elio could just choose a 60-70hp 3 cylinder already out there with no turbo and call it a day.
I'll give you an example and we will use a VW Jetta as for comparing what cars used to give:
1986 Gas Manual - 23/31 and it had a 1.8l 85hp
1986 Diesel Manual - 31/40 and it had a 1.6l 50hp
1986 Turbo Diesel Manual - 31/38 and it had a 1.6l 70hp
2019 Gas Manual - 30/40 and it has a 1.4l 148hp
So, over 33 years VW has a Jetta which makes 63hp more with a motor that's 400cc less and gives 7/9 better on fuel mileage.
They don't sell the Jetta in Europe but if I go with the Golf I can get an idea.
2019 Gas Manual - 5.4l/100km and it has a 1.5l 150hp
2019 Gas Manual - 4.7l/100km and it has a 1.0l 115hp
As you can see a 1000cc 3 cylinder VW TSI motor has better mileage over the 1.5l 4 cylinder. So that's about 13% improvement. If you equated it to the US Jetta and how we compute MPG, then it's 34/45 if they offered the 1000cc 3 cylinder turbo. On the other hand, we lived with 85hp back in 1986 but could we live with 115hp today in a Jetta. Probably not. On the other hand, with it pushing twice the air and weighs twice as much, that 1.0l TSI motor in a Elio would be kick butt. Then if they used the 7 speed DSG transmission, you get paddleshift and even better mileage.
If people don't want better mileage and performance, then I guess that's where we should go.
