I don’t like the small engines because the ideal to move a 1400kg car is minimum 125HP, and I can get this power with a 1.0 or 1.2 engine, but to get this power you need to rev more the engine, needing more fuel, and the reliability decreases (because in the <1.8L engines I use low friction pistons in the non-sportive engines or low-fuel consumptio engines), and setting a turbo to be smooth, minimum lag and the max torque under 2000 rpm you can’t make, for example, a 1.0 125hp engine without lag.

I know what you mean…, I read urban on the post and never seen that the urban thing weighs 1400Kg
Yep, an engine with that little displacement needs a turbo, but without a compressor helping at low revs is really tricky a turbo sys without its respective lag (till around 2000 revs). I think that a turbo with an ‘economic profile’ works relatively good in Automation (might kick in a bit sooner, but its ok) e.g.
[quote=“vmo”]I’m developing a new 2.0 turbo with 134HP (134 HP in a 2.0 engine! Imagine the power in a 1.0 engine), but the max torque (at the moment, 174N*m) starts at 1600RPM and ends at 4500RPM, low lag, very smooth power delibery and had force at all RPMs, since the start, needs low fuel, but I can’t make more to make a turbo engine with a minimum of 85HP/L to up, delivering the max torque under 2000-2500RPM without lag.
But don’t panic: all the Montes models will be available in turbo and N/A engines, and you can get, for example, the 2.0 N/A or the 2.0 Turbo.
I’m agree that being an urban car you need a smooth power delivery, and a NA engine accomplish that goal in the best way possible.
