Background
The Pagoda roofed Mercedes Benz SL, the W113, did good business for Mercedes-Benz in the all-important North American market. Around 40% of all W113s – 20,000 or so – ended up stateside. By the mid 1960’s, however, the winds of change were not so much blowing but howling through the US auto market. Lawyer, Ralph Nader, released a book in 1965 entitled “Unsafe at Any Speed.” This best-selling exposé focussed on the appalling safety record of the Chevrolet Corvair. By association it cast aspersions over the US’s main motor manufacturers for failing to introduce readily available safety measures, merely to bolster their bottom lines. Nader’s book is widely credited for ushering in a safety-centric regulatory structure that would endure for a couple of decades.
By the late 1960’s car manufacturers were pre-emptively cancelling planned convertible models left, right and centre. The expectation was that especially they would prove impossible to build to comply with the impending, draconian regulations or be banned outright. With the US such a key market for Mercedes sports models, this upheaval very nearly killed off a convertible successor to the W113, too, with the Mercedes board campaigning for hardtop-only release. Ultimately a persistent head of R&D, Hans Scherenberg, won his case and an open convertible with a detachable hard-top was finally green-lit. There was an important and non-negotiable proviso, however - this convertible would need to be safer than any built by anyone to date.
And so it was, with the R107 launching in 1971 with a windscreen surround that could support the weight of the car in the event of a roll over and ample crumple zones incorporated into the sleek Friedrich Geiger design. In some ways Nader’s book had done the German marque an unintended favour. Most other companies had cancelled their upcoming convertibles, effectively gifting this popular and prominent market segment to the new SL. The R107 went on to become the company’s second most long-lived model after the G Wagen and sold well over 300,000 units during its 17-year production life, dwarfing the 49,000 achieved by its esteemed predecessor. Of course, the car enjoyed great success in the USA, too, with over 60% of R107’s being sold there. We wonder if Mercedes-Benz ever thanked Nader for all his unpaid help in making the R107 such a boulevard icon.
