300 SL Panamericana - Front

Automobiles don’t look like they used to. Granted, modern cars perform better, last longer, and have a few points shaved off their drag coefficient; but in too many cases, they’ve sacrificed aesthetic appeal for those things. Don’t get me wrong, if I could have only one, I’d choose substance over style… but ideally I’d want both.

Wouldn’t it be nice if you could take a 1966 Maserati Ghibli and make it perform like a 2009 Maserati MC12; or a 1968 Corvette drive like a 2009 ZR1; a 1966 Lamborghini Miura zip like a Gallardo; a Nissan 240Z go-go like a Nissan GT-R; or an original Jaguar E-Type drive like, well, anything but a modern Jaguar. You get the picture. Old style combined with modern quality components, that’s the dream, and that’s exactly the point of the 2009 Gullwing-America 300 SL Panamericana. Engineer Arturo Alonso is the man behind the concept and his idea is to create a near perfect replica of the original Mercedes 300 SL using 100% modern technology.

Check out the proposed specs and a gallery of pics:

The original Mercedes 300 SL

In 1955, the 300 SL was pretty much the car to beat. It was the fastest production car on any road, anywhere. It was light, high quality and high-tech for the time, being one of the first cars to use direct injection (fuel injection directly into the combustion chamber). And it was stunningly beautiful. It made a huge impact in the auto world. In fact, the modern Mercedes-Benz SLR McLaren is usually thought of as the “spiritual successor” to the original 300SL.

Fast-forward 50+ years, and Arturo Alonso wants to bring back the aesthetics of the of the original 300 SL, with all new componants. His 2009 Gullwing-America 300 SL Panamericana, if it ever goes to production, will be as ultra-modern as it can get. Not only will it have a six speed trans and the 5.5 L Mercedes engine already found in the SLR (although tuned to put out 370 hp and a huge 391 foot pounds of torque), but even the exterior and chassis will be high tech. It’ll supposedly use a powder coated RHS steel reinforced chassis and have a body composed of a 1/2 millimeter thick layer of sprayed aluminum coated with an epoxy, and then covered with multiple layers of 7oz woven glass cloth.

The interior will sport a four-spoke leather wheel, a start button, high-end stereo system, and a four-point racing harness. High end all around, except for, of course, the speedometer cluster. Alonso says the car will keep the original instrument panel from the 300SL.


Christ, I hope this car makes it to production. Check out the image gallery and the official press release at the bottom.
