2016 BMW Z4

Andrew Newton Preview:

The BMW Z4 was first introduced at the Paris Motor Show in 2002 as the Bavarian carmaker’s replacement for its previous rear-drive, two-seater convertible offering: the Z3. The Z4 was ...

John Goreham Preview:

This year the Porsche Boxster will turn 20. It was back in 1996 that a new, midengine, convertible-only roadster joined the Porsche lineup with a starting price under $40K. At the time...

I purchased a 2015 BMW 28l. I really enjoy this vehicle as it is reasonably quick and handles well. My only co...
Power Ranked 2016 Audi TTS better.
"Ideally, it would have been a more apples to apples comparison had I driven the TT, not the TTS as the TT is more in line with the BMW Z4 28i. That being said, the TTS was much faster. "
Handling Ranked 2016 Audi TTS better.
"The Z4’s rear-end was was a bit loose when pressed in turns, the TTS was more stable in turns."
Looks/Style Ranked 2016 Audi TTS worse.
"Both vehicles are good looking. However, the Z4’s roadster style is classic and unique, whereas many vehicles have the TT styling."
Front Seats Ranked 2016 Audi TTS worse.
"The front seats in both vehicle were comfortable and up to the task. Subjectively, I liked the Z4’s seats slightly better."
Back Seats Ranked 2016 Audi TTS better.
"Simply because the Z4 doesn’t have rear seats. "
Cargo Capacity Ranked 2016 Audi TTS better.
"The TTS has a hatchback and the rear seats can be lowered to provide more storage space. Unfortunately, the Z4’s trunk space is limited with the roof up and very limited with the roof down."
Family Car Ranked 2016 Audi TTS better.
"I do not consider neither car to be a family vehicle, however the TTS is a 4 seater."
Value Ranked 2016 Audi TTS worse.
"The Z4’s hardtop convertible give you the security of a coupe and the convenience/ freedom of a convertible. Additionally, the Z4 (28i) gets better gas mileage than the TTS."
Would Buy Ranked 2016 Audi TTS better.
"The TTS’ interior was more up to date than the Z4. And the TTS has all wheel drive capability. "

Cramped, rough ride, limited cargo space. Beautiful car!
Handling Ranked 2014 Jaguar F-TYPE S Convertible RWD better.
"Cannot say why it handles better, but it does."
Value Ranked 2014 Jaguar F-TYPE S Convertible RWD worse.
"A beautiful, well-proportioned car priced where it should be."

Reasonably priced & better looking. Soft tops look cheesy!
Handling Ranked 2016 Porsche Boxster S better.
"Mid engine car."
Value Ranked 2016 Porsche Boxster S worse.
"All year round hard top cabrio. Faster with a tune. Heated steering wheel with winter package. Much less expensive with Italian styling."
