A 1.2 sqm roof is made for the Smart Fortwo vehicle.

The Pulse and Passion versions of the 'Smart Fortwo' vehicle now have, an “extremely sturdy and breakage-resistant� fixed high-strength 1.2 square metre polycarbonate panoramic roof that is adhered to the Tridion safety cell frame.

Webasto supplies the roof module, which has half of its polycarbonate area transparent. Made with 4.5mm thick polycarbonate, the company says that there is a 50% weight saving over an equivalent module designed with glass.

Supplied in a slight tint, 60 percent of the sun's energy is reflected and 100 percent of UV radiation is blocked by the transparent glazing, while a polyester sunblind is provided for additional protection.

Makrolon AG2677 PC is claimed to block UVA, UVB & UVC. The polycarbonate roof is a blend of Makrolon and Bayer Bayblend* DP T95 MF. The unique formula helped create the largest roof of it's type used in any production vehicle, 13 sq. ft.

On these car forum sites there always is a argument or two about anti tampering laws and SEMA's fight for aftermarket producers. I am generally against strict federal regulation. This above is an example of a Federal law on the books that is not well known and obviously not enforced to any serious degree... please carefully read the bulleted prohibitions and understand that the underlined sections also include all of us end users or owners.

Generally what I caution on these forums is to not get outrageous with warranty claims and try to be reasonable with loud mufflers... My reasoning is; there are already the Federal Laws out there and it would not take much for angry neighbors to ask legislators to demand enforcement and stricter laws...

Luckily our neighbors are used to the Borla Stingers on the Vette (and I don't have to go into work at 6:30 am anymore)
