The article itself is muddly and confused and anyone plowing through it would do well to read the comments, several of which expose some of the muddle and confusion.
Just one issue alone illustrates how weak the article is; there is no mention of the ISX12G engine. Nobody who expects their view on the future of WPRT to be taken seriously can ignore this new engine. It is aimed at a different segment of the market from the smaller ISL G and many regard it as the engine that the regional trucking companies have been waiting for. The next few quarters will show whether this view is correct.
