Mercedes-Benz W150 770 Grosser Cabriolet (1938 - 1943) & Messerschmitt Me 410 Heavy Fighter (1943)

The Mercedes-Benz 770, also known as the Großer Mercedes (large Mercedes) was a large luxury car built by Mercedes-Benz from 1930 to 1943. It is probably best known from archival footage of high-ranking Nazi officials before and during World War II, including Adolf Hitler, Hermann Göring, Heinrich Himmler and Reinhard Heydrich.

Series II - W150 (1938–1943)

The 770 was substantially revised in 1938, resulting in the new internal designation of W150. The all-new chassis was made with oval section tubes and was suspended from coil springs all around, with independent suspension at front and a de Dion axle at the rear.

The engine had the same basic architecture as that of the W07, but it had been tuned to produce 155 brake horsepower (116 kW) at 3000 rpm without supercharging and 230 brake horsepower (170 kW) at 3200 rpm with. The transmission now had five forward ratios with a direct fourth gear and an overdrive fifth.

In 1938 the huge W150 is thought to have been the most expensive German passenger car for sale up to that time, though it appeared on no price list: the price was published merely as "auf Anfrage" ([available] by request). 88 W150-series cars were built before chassis production ended in 1943. The last cars were bodied and delivered in March 1944.

There is some interesting information regarding the previous owners of 770s, including cars used by Adolf Hitler during the era of the Third Reich.

This Lego miniland-scale 1938-1943 Mercedes-Benz W150 770 Grosser Cabriolet has been created for Flickr LUGNuts' 103rd Build Challenge, titled - 'The Fabulous Forties!' - a challenge for any vehicle produced through the decade of the 1940s.

Further images will be loaded illustrating the Grosser with its contemporary Daimler-Benz-engined Messerschmitt Me 410 WWII Heavy Fighter. This plane was flown by the Luftwaffe during WWII. The Me 410 was powered by a Daimler-Benz 603 aero engine (under the same parent company as Mercedes-Benz car division).

Messerschmitt Me 410

The Messerschmitt Me 410 Hornisse ("Hornet") was a German heavy fighter and Schnellbomber used by the Luftwaffe during World War II. Though essentially a straightforward modification of the Me 210, it was designated the Me 410 to avoid association with its notoriously flawed predecessor.

Design and development[edit]
Development of the Me 210 had been under way since 1939 but the aircraft proved extremely unstable and was never considered for full-scale production. Modifications to the layout produced the Me 210C and 210D, which proved somewhat superior. As studies progressed on the Me 210D, and with a separate parallel attempt to improve upon the 210 with the Messerschmitt Me 310 in the second half of 1943 — which provided almost no aerodynamic improvement over the 210's risky handling qualities — it was instead decided to introduce a "new" model, the Me 410.

The major change between the Me 210 and 410 was the introduction of the larger (at 44.5 litre, 2,715 in3 displacement) and more powerful Daimler-Benz DB 603A engines, which increased power to 1,750 PS (1,730 hp, 1,290 kW) compared to the 1,475 PS DB 605s used on the Me 210C - the interim Me 310 design experiment actually used the DB 603 powerplant choice first. The engine performance increased the Me 410's maximum speed to 625 km/h (388 mph), greatly improved rate of climb, service ceiling, and most notably the cruising speed, which jumped to 579 km/h (360 mph). It also improved payload capability to the point where the aircraft could lift more war load than could fit into the bomb bay under the nose. To address this, shackles were added under the wings for four 50 kg (110 lb) bombs. The changes added an extra 680 kg (1,500 lb) to the Me 210 design, but the extra engine power more than made up for the difference.

The new version included a lengthened fuselage and new, automatic leading edge slats, both of which had been tested on Me 210s and were found to dramatically improve handling. The slats had originally been featured on the earliest Me 210 models, but had been removed on production models due to poor handling. When entering a sharp turn, the slats had a tendency to open, due in part to the turn causing a drop in air pressure at the leading edge of the wings, analogous to the low pressure activation the slats were designed for in a slow landing approach (this problem was first observed on the Bf 109V14 and V15 prototypes for the Bf 109E), which added to the problems keeping the aircraft flying smoothly. However, when the problems with the general lateral instability were addressed, this was no longer a real problem. The wing panels of the earlier Me 210 had been designed with a planform geometry that placed the aerodynamic center in a rearwards direction in comparison to the earlier Bf 110, giving the outer sections of the wing planform beyond each engine nacelle a slightly greater, 12.6° leading edge sweepback angle than the inner panels' 6.0° leading edge sweep angle. This resulted in unreasonable handling characteristics in flight for the original Me 210 design. The new Me 410 outer wing panels had their planform geometry revised to bring the aerodynamic center further forwards in comparison to the Me 210, thus making the leading edge sweepback of the outer panels identical to the inner wing panels with both having identical 5.5° sweepback angles, which improved handling.

Deliveries began in January 1943, two years late and continued until September 1944, by which point a total of 1,160 of all versions had been produced by Messerschmitt Augsburg and Dornier München. When it arrived, it was liked by its crews, even though its improved performance was not enough to protect it from the swarms of high performance Allied fighters they faced at this stage of the war.
