I was tempted to put a note on the end saying that despite having won a race, they're not competing for wins at any other races (which is what I would normally mean when talking about a potentially race-winning car). In their current form, it's hard to see either of them winning a race unless the conditions suit them and no one else, which is also very unlikely. Much like Torro Rosso in 2008 when Vettel won at Monza.
The phrase may not be technically correct, but it gets the point across.
