The new Steinmetz tuning program for the latest 2007 Opel Astra TwinTop convertible does not only look stylish and cool. It also features a decent engine upgrade balancing muscular appearance of the plastic body kit with some real power.
According to the German tuning specialist’s official press release, Steinmetz adds extra power to both diesel and gasoline engines.
For example, Opel Astra TwinTop‘s 2.0-liter turbo’s maximum power output pumped up from standard 200 to more impressive 230 hp, and its maximum torque has also risen from 262 @4200 rpm to 302 Nm @ 4400 rpm.
The 1.9 CDTI now delivers 175 hp instead of its original 150 hp and produces maximum torque of 380 Nm — that’s 65 Nm more than an unmodified engine can give.
I am not sure whether the standard-issue gearbox will be happy about such an abrupt rise in available torque, but the driver will surely notice how faster the car becomes with the engine upgrade.
With all these upgrades, the Opel Astra TwinTop’s top speed has risen from standard 230 to 238 and from 208 to 212 respectively. The 0-100 km/h acceleration time has also been slashed by a couple of seconds.
The most interesting part of the aerodynamic package is the new two-piece rear spoiler.
Although looking a little bit too subtle (especially when compared to larger than life garden benches usually installed by other tuners,) Steinmetz’s new spoiler provides the Astra TwinTop’s rear axle with additional down force and at the same time does not hurt one’s eyes, looking just like it was meant to be there from the very beginning.
Thanks to its shape, it also doesn’t produce excessive aerodynamic drag thus making the car more fuel efficient.
Of course, there is also a set of bicolor wheel and tyre combinations, available in different sizes from 16″ to 19″.
