Also based on this latest report, we're given another reason why Nissan turned down Mercedes' offer: Infiniti already has the goods, and it's called the Q60. Work is also underway on the next Q60, which will share a rear-wheel drive platform, engines, and overall electronics with the new Z car. Dimensionally, both cars will be very similar, meaning the new Z car will be slightly larger than the 370Z. And yes, Nissan will launch a new Z roadster as well, though that's not expected to happen before 2021. So, when will we catch our first glimpse of the new design? Autocar believes the new Z car will appear in concept form next October at the Tokyo Motor Show.
