Such a car exists, lol? [emoji6]
Yep, if you don’t spend your life looking at the world with blinkers on its amazing what you’ll see
Just because it doesent achieve the claimed mpg, and small turbos generally don’t apparently, does not mean the TA is not a good engine.
I do t think anyone is saying “it’s a crap engine” but the point of this thread is that these new small turbo engines are not really getting any better economy figures to an equivalent non turbo engine.
They go a bit faster 0-60 then their equivalents, but they add several layers of complexity and this in turn creates more potential for failures and makes them therefore less reliable. You can throw as many stories as you like about, regarding personal experiance of how reliable your own TA was, but no 1.2 500 ever suffered a turbo failure or a solenoid valve failure.
It’s interesting to note that the twinair set up is not being used on the newer engines the 1litre 3 cylinder and the 1.3litre 4 cylinder, in places like India and South America, they are using conventional valve timing set ups, this is because 1. The emissions requirements are not as strict as here in Europe, which in one of the reasons such a complicated engine has become essential here. And 2. The system is too delicate to cope with the abuse those engines would get, wrong oil used regularly, irregular serving or not being serviced at all. Dusty hostile environments with rugged terrain and in some cases no roads. The TA setup is definately not a robust, more complicated and more expensive to maintain and and repair.
It’s non opinion these are all verifiable facts.
