Bovensiepen Unveils 435hp BMW Z4-Based Spider Limited to 99
Bovensiepen has made a special sports car called the Spider.
It is based on the BMW Z4 M40i.
The car has been changed extensively by the specialist tuner.
It makes 435hp and 580Nm of torque.
That is more power and torque than the regular Z4 M40i.
Only 99 cars will be built around the world.
The car will not be sold in India through an official dealer or import route.
It shows how much extra performance can be added to an existing car design.
Bovensiepen has revealed the Spider, a heavily reworked BMW Z4 M40i.
The roadster produces 435hp and 580Nm of torque.
That represents increases of 95hp and 80Nm over the standard Z4 M40i.
Production will be limited to 99 hand-built examples worldwide.
The Spider is not planned for India because Bovensiepen has no dealer presence or import pathway there.
