We think of BMW as the maker of some of the best sports sedans, but its put out impressive roadsters over the Seventy-five years to be exact. The auto manufacturer has been two-door open-seaters for three of a century now, starting 315/1 Sports model was unveiled at the 1934 Berlin Show followed by the more 319/1.

Two legendary roadsters next, starting with the 328 in 1936 that was bred on the and the classically-styled 507 in the late 1950’s inspired the next half of BMW two-door ragtops.

Munich. The style has changed, but not the Many German motorists see not just as a comfortable and fast of transport, but also as a sporting These are people who, they see an aerodynamic car body a long and sleek engine as well as a speedometer extending all the way to 150 feel that strong for wide open roads perfect for driving fast, for passes just begging to be and for ompetitors so easy to overtake.

It was with these words BMW announced the Company’s first roadster in 1934. And indeed, concept with its six-cylinder unit was destined to shape the of the brand, extending all the way to the current BMW Z4.

The point for this development at the Berlin Motor Show in May Here, together with the BMW 315 BMW for the first time presented the of a Sports Roadster with attractive lines. Right the long and sleek engine there were two sports tailored to the driver and front protected by the low, raked and an mergency roof.

The rear end out in an elegant sweep to the back of the adding a particular aerodynamic with excellent streamlining.

The grille on this two-seater was much further to the rear on the Saloon, with mighty, front wheel arches on beneath the doors into the wheel arches. To reduce air to a minimum, the rear wheels fully covered, while the of the car itself rested on an electrically steel-pipe double frame three crosswise box elements.

Front suspension was made up of the track spring, wishbones down and hydraulic lever-type The rear wheels, in turn, mounted on a live axle semi-elliptic springs and hydraulic dampers.

Small but hot: power unit displacing 1.2

Both the saloon and the sports car powered by the same outstanding a 1.5-litre straight-six developed out of the originally featured in the former BMW The crankcase and cylinder block of outstanding engine were of one single piece, the engine one camshaft beneath the block, tappets operating the vertical valves aligned in series via arms. The intake and exhaust finally, were on the same

A feature quite unusual is the different distances between the

cylinders, with the second and and, respectively, the fourth and cylinders being further the space in between being for the crankshaft and amshaft bearings.

The without any counterweights therefore ran in bearings, just like the

This was however not the reason for particular design and configuration, was rather attributable to the assembly at the time, with the crankshaft completely pre-assembled together the connecting rods and pistons. And the pistons, as a result, had to be inserted beneath, the main bearings for the had to remain outside of the cylinders, not into their contour As a result, the main bearings had to be between cylinders spaced out at a distance.

While this unit delivered maximum of 34 hp on the saloon with its two carburettors, output of the six-cylinder in the BMW 315/1 model was 40 hp. And the standard of efficiency was quite exceptional, BMW’s proudly stating that beautiful and fast sports car only 102 litres of fuel on 100 km, oil consumption between 0.1 and 0.2 kg. So in terms of costs, it is no more expensive a small car far lower down in the

With the public simply in love with the BMW 315/1, BMW to build the car in a small series because the Company wanted to a more powerful entry the prestigious world of motorsport. in summer 1934, therefore, the attractive BMW 315/1 was retailed at a 5,200. reichsmarks. The production differed from the prototype through the modified arrangement of the and side ventilation grids the place of the bent openings featured on the first model.

Outstanding success in motorsport.

a top speed of 120 km/h or 75 mph, the BMW Roadster was one of the really serious in the sports car market at its time. BMW’s story of success on the track quickly took on greater significance with new model, the BMW 315/1 achieving its significant success in the International Alpine Rally.

The starter for this rally in Nice was up of 127 truly outstanding cars at daily race sections of kilometres to be covered at a minimum On the fourth day there was an additional test at Stilfser Joch.

covering precisely 2,867 or 1,778 miles, 96 of the 127 cars had originally entered the race the finish line in Munich 66 without having lost one The five cars entered by the BMW Team were the only in their class to complete the Alpine Trophy without one penalty point, the BMW 315/1 Richard Brenner/Albert Kandl/Ernst v. finishing first in their

Only 230 units of the BMW 315/1 completed by mid-1935, many of going to private drivers. One of was Ralph Roese, a BMW works for many years, who built a BMW 315/1 Special. This was a re-build of the 315/1, the highly engine ultimately developing no than 136 hp in a brand-new race car weighing just 380 kg or 838 lb.

Given of this kind, it is no surprise this racing car finished in its very first race at in 1936, a staggering 17 kilometres of the competition. Understandably, this model remained a great over the years until winning the German Road Championship in 1939.

Achieving kind of success, both the and the Company soon started

for more: a car in the prestigious category up to two And so it is no surprise that another, more powerful version of the BMW the 319/1 entered the market in 1934. Identical in its looks to the BMW with the exception of the air vent on the compartment, the BMW 319/1 was powered by a tuned to 55 hp and benefiting both larger displacement and three downdraught carburettors.

Obviously, an like this was easily to cope with a two-seater just 780 kg, accelerating the roadster in trim to a top speed of pproximately 135 or 84 mph. At the same time was of course a truly exclusive car due to its price of 5,800 reichsmarks. from 19341936 therefore to just 178 units, with the BMW again bringing home success in motorsport.

The climax of the pre-war era: the BMW 328

In the mid-30s, production roadsters and cars were still similar in technical terms and was still the ideal place to the performance and reliability of a production But to keep up with the competition, BMW had to build cars with power and muscle. So BMW’s looked for ways and means to increase engine output increasing engine size.

And found the solution the M328, the powering the legendary BMW 328 sports car in

Right from the start in its at Nürburgring on 14 June 1936, new

roadster literally pulverised the most powerful supercharged This outstanding success was to the well-balanced combination of superior power and cutting-edge suspension characteristic of BMW roadsters to this 80 hp in the regular version and low weight of 830 kg or 1,830 lb gave this roadster superior performance impressive today.

With the BMW 328 initially being restricted to as of mid-1936, production of the series started in spring 1937. And so high-performance sports car was driven not by BMW’s works drivers, but by private customers since, and above racing, it was very suited for everyday use. And its top speed of 155 km/h or 96 mph, was indeed one of the fastest cars on the back then.

But again, the BMW 328 remained a very rare with only 464 units
