Part of this is the lower numbers of Cruze diesel that Chevy has produced but I'm mystified why the Cruze diesel hasn't sold better. About 6,000 Cruze diesels were sold in the last year, 2% of Cruze sales. Jetta TDI sold in the last year totaled about 46,000 and has been a much larger percentage of Jetta sales. I'm not sure if they counted Jetta Sportwagen but even still.. Mpg and power are about the same. Looks are subjective. The Jetta has the option of DSG or manual, the Cruze has automatic only. Jetta has bigger back seat. Cruze has higher trim level at the same price. Cruze uses older design HPFP and is louder but may be more reliable. I think it's kind of a wash and pricing is also about the same.
