FCA sales volume for the year is up 6%, but according to Tim Cain without Jeep the rest of FCA is down 2% YoY.
Consider this, in the US total auto sales across all brands rose 15%, FCA brands not named Jeep only posted a minuscule 1% increase YoY. Cain offers a stunning observation, 40% of FCA's US volume is dependent on Jeep, no wonder the UAW didn't get their way until they threatened to essentially halt Jeep production.
Even RAM, Jeeps perpetual partner for growth at FCA, has struggled in the second half of 2015. RAM has lost 2% of its overall market share through September. 2% isn't much, sure, but when the overall market for pickup trucks has steadily climbed throughout the year, gaining 11% YoY in September, a regression is certainly concerning.
As for Renegade vs 500X, the Jeep is outperforming the Fiat by 11 sales to 1 and Fiat is shouldering a massive 193 day supply of 500X's.
