Porsche Boxster GTS vs BMW Z4 Roadster sDrive20i (2014): 37 facts in comparison

1. Has dual-clutch transmission

A dual-clutch transmission (DCT) is an automated manual transmission that allows the driver to control gear-shifts themselves or to let the computer decide. Upshifts are extremely fast, resulting in smooth acceleration, and due to the uninterrupted power flow it also has the benefit of increasing fuel efficiency.

9. Has rear-wheel drive

Rear-wheel drive benefits from increased traction when accelerating, as the weight of the vehicle shifts to the rear over the drive wheels. The weight of the car is also more evenly distributed, resulting in improved handling.

10. Has a rear-view camera

A rear-view camera (also known as a back-up camera) provides a view of behind the vehicle, helping to prevent accidents. It is particularly useful in vehicles with large blind spots such as pickup trucks.

13. longer wheelbase

The wheelbase is the distance between the center of the front and rear wheels. A longer wheelbase provides the car with more stability and a smoother ride (although a shorter wheelbase can provide more responsive handling).

16. lower coefficient of drag

The coefficient of drag is one measurement of how well air travels around a vehicle. A lower value means it is more aerodynamic and the engine doesn't have to work as hard. It can result in faster speeds and lower fuel economy.
