Executive limousines are a different breed, and the Infiniti Q70L has its own distinct take on the mid-size executive limo segment. Imagine you took a mid-size, rear-wheel-drive, luxury sedan and stretched its wheelbase a few inches, giving you more rear-seat legroom. Understandably, these cars offer passengers first-class space and amenities. But, does Infiniti have what it takes to earn business in this ultraluxe segment? Established players from Europe have these cars down to a science, and the Q70’s Japanese rivals make a solid case for themselves, too.
