A Uncommon Look At The Hydrogen BMW 5 Collection E12, The 520h


BMW’s hydrogen efforts go way back to the late Nineteen Seventies with a prototype based mostly on the first-generation 5 Collection Sedan. The E12 within the 520i specification saved its inner combustion engine nevertheless it was modified to run on liquid hydrogen. A brand new video from BMW Group Traditional presents us a uncommon take a look at the 520h developed in collaboration with the German Aerospace Analysis Institute.

You may think about it was far much less sensible than the gasoline-fueled 520i of these days as a result of the hydrogen tank occupied many of the trunk area. The tank needed to be specifically insulated to guard the hydrogen and retailer it for so long as attainable at a temperature of -250 levels Celsius (-418 levels Fahrenheit).

Whereas later hydrogen BMW prototypes had been engineered to run on each gasoline and hydrogen, the 520h used solely the latter.  Curiously, we additionally get to see a black 7 Collection E23 from 1980 with a hydrogen tank good for 300 kilometers (186 miles) of vary. The video takes us on a tour of the opposite take a look at autos, together with the E32 7 Collection 735i from 1988 with a greater format for the reason that hydrogen tank didn’t eat as a lot into the cargo space.

 

Then the 750hL comes alongside within the video as a particular E38 from 2000 with a hydrogen-fueled V12 engine producing over 200 horsepower. Solely 15 vehicles had been ever made, and these had a high pace of greater than 143 mph (230 km/h). The 5.4-liter engine produced 204 horsepower and ran on gasoline and hydrogen, masking 250 miles (402 kilometers) with a full 140-liter hydrogen tank earlier than switching to gasoline.

The preferred of the lot is certainly the BMW Hydrogen 7 from 2006, based mostly on the 760Li (E65). It too had a V12 engine, dialed to 260 horsepower. It was sufficient punch for a 0 to 62 mph (100 km/h) run in 9.5 seconds and an electronically capped high pace of 143 mph (230 km/h). The “world’s first hydrogen-powered luxurious saloon automotive” because it was referred to as again within the day had 125 miles (201 kilometers) of vary from the liquid hydrogen tank holding 8 kilograms of gas. The 74-liter gasoline tank offered an additional 300 miles (483 kilometers) of vary.

We additionally get to see the 2004 H2R File Automotive with its 6.0-liter V12 engine borrowed from the 760i. The carbon fiber-bodied machine set 9 world data: flying-start kilometer, flying-start mile, standing-start 1/8 mile, standing-start quarter mile, standing-start half kilometer, standing-start mile, standing-start 10 miles, standing-start kilometer, and standing-start 10 kilometers. It had 232 hp on faucet, giving it a 0-62 mph (0-100 km/h) dash in 6 seconds and a high pace of 187.62 mph (301.95 km/h).

With the iX5 based mostly on the current-generation X5 luxurious SUV, BMW remains to be pursuing hydrogen know-how. In late 2022, BMW Group chairman Oliver Zipse promised: “On this decade there can be a viable product from BMW with hydrogen. You will notice that. We imagine in hydrogen for a lot of causes. We imagine that – and I’m talking now from the BMW aspect however that finally ends up being for each model within the Group – if you wish to experience emissions-free and also you do not need a charging station, that is the one risk now we have.”
