When the atomic bomb was used 75 years ago

About 100 years, people shocked the totality of the first world war. Nobody had to introduce millions and but million dead as a result of a military confrontation. This mass destruction was only possible through new technologies (planes, machine guns, tanks, poison gas, etc.To). Worse can not come, so people thought. But in fact, she was waiting for a much worse horror: a single bomb with which hundreds of thousands of people had dead. Exactly 75 years ago, on the 6th. August 1945, the us militar threw a first atomic bomb on the japanese city of hiroshima. Three days later formed an atompiluce over nagasaki.

New battery type: 0 to 80 percent in 5 minutes

Plane for electric sports cars with breathtaking performance data is now almost nothing more. With his study mark zero, the swiss-german start-up piech automotive at the geneva motor show in this marz still provided for a view.

Luxury light

Munchen, 10. June 2015 – the mercedes s-class presented two years ago has properly submitted in some ways. Since the very rough spray in this class are over, the manufacturers hardly remain as the design to adapt to the time taste and install even more electronics. This recipe also pursues bmw with the next edition of the 7 series.

Core

The new notice sign of the munchner does not set up luxury or pomp, but on the core competence of the bavaria – spab, dynamics and efficiency. While the s-class with optical prasenz and opulent luxury, to maybach and pullman versions, to attract customers from all over the world, it will take the 5.10 meter long 7 bmw (long version: 5.24 meters) significantly more subtle. There are only two 7-year variants that differ only in the long of the wheelbase. Despite the complete new development with the integration of abundant carbon, the design is largely based on the successful transaction.

Especially from the beginning, the new top model with its flat front and headlamps in led or laser technology slim. That should probably be visually underlined that the sixth generation has closed.

Mazda uses hybrid technology from toyota

Mazda uses hybrid technology from toyota

Koln, 29. Marz 2010 – toyota will be true "in the field of alternative drives" work together with mazda. The license agreement signed today in japan provides for providing hybrid components of the toyota prius, which mazda wants to combine with its own internal combustion engines. Specifically, this apparently means that mazda relies on a power-branched hybrid and does not like many competitors on a parallel hybrid. Mazda will not refer to the hybrid components, including the planetary gearbox, but by toyota, but by the suppliers of the world-growing car manufacturer. Among other things, the gearbox was allowed­manufacturer aisin.

Combustion engine of mazda

Both companies do not give any further details price, but the interface seems to sit between hybrid components and internal combustion engine. Mazda wants to combine the system with its so-called sky engine technology, which is currently still in development. "Sky" is mazda’s name for modern otto and diesel engines, the 15 or. 20 percent more economical than comparable variants in the current mazda motor program. In the gasoline engine, among other things, direct injection, high compression and friction reduction should contribute, in the diesel above all an optimized combustion process.

In conjunction with the hybrid drive is certainly to be expected the use of the gasoline, which should be introduced into the market as the sole drive in 2011. The new mazda hybrid vehicle is to be developed and manufactured in japan and be offered there from 2013. According to a report of the financial times however, mazda hopes to offer the car later on other market.

Opels saving contribution

Opels saving contribution

Russelsheim 7. August 2013 – with the 1.0 sidi now appears opel’s first small aggregate in the course of the rough renewal. He sparks with modern downsizing through direct injection and turbocharging without being complicated in excessive. Suitable for the coming small engine class a six-speed manual transmission was presented.

After opel in 1997 with the 1.0 ecotec suction motor with 54 to 60 hp in corsa was a pioneer in terms of efficiency, this unit has not been ordered since 2009. The small three-cylinder was finally surprised with the growing mass of the former small car corsa. Initially, he brought the approximately a tonne of heavy corsa b, but it is still worthy, but adequately sparingly and comfortable in swing and highlighted with a now not self-reliable multipoint injection, four-valve technology and hydrostobs yet in this class. In view of increased use of performance and efficiency, a completely newly constructed successor appears.

Performance of the process doubles

The 1.0 sidi (spark ignition direct injection) is to be introduced in the opel adam next year. This is not a minute to early in the face of the motors from the day before yesterday in a car with so high consignment claim. Currilitations like the tension band bleau of the process planned by the renowned engine developer fritz indra can no longer be found, but a balancing shaft and – much more important – current downsizing technologies. Father, after its role model, another three to four-cylindrical motors up to 1.6 liters should arise.

Grande punto is now called punto evo

Grande punto is now called punto evo

Frankfurt am main, 31. August 2009 – sounds great: the new fiat punto is called evo, which stands for evolution or old-new­german facelift. After all, the punto evo has more new technical features than the rather familiar-looking evo would suggest, such as a rather bold engine technology with which fiat wants to make gasoline engines more efficient than before. The evolutionary punto will be on display at the iaa in just under three weeks, from 17. To 27. September 2009 in frankfurt.

A little rougher and beefier

According to fiat, the front and rear of the punto have been "completely redesigned". The visual appearance appears chunkier and wider. The punto is also three centimeters longer and now comes to 4.06 meters. Width (1.69 meters), height (1.49 meters) and wheelbase (2.51 meters) remain unchanged. The cornering light is a new optional feature: this illuminates a tight bend better when turning in by switching on the fog light inside the bend; this function was first available on the new seat ibiza, by the way. Inside, the instrument­the interior has been redesigned and the seats are also new. Additional storage compartments to increase comfort.

Seven airbags and esp as standard

Seven airbags are fitted as standard in the punto evo to ensure occupant safety – a driver’s knee airbag is also included. Esp is also always on board. And for steep ramps or real mountains, there is a hill-starting aid that maintains the brake prere for a short time after the brake is released on the slope, here too the ibiza was a pioneer. For entertainment and navigation fiat has cooperated with the dutch navigation specialist tomtom. The result is a further developed blueme, in which the navigation, hands-free system and entertainment functions can be operated via a removable touchscreen.

Mazda sporty and economical in geneva

Mazda sporty and economical in geneva

Geneva, 2. February 2009 – mazda shows at the geneva car salon of 5. To 15. Marz 2009 two new model variants of the mazda 3 coming in fruhsommer. On the one hand, the top model is celebrating 3 mps its world premiere, on the other hand a new two-liter gasoline engine will be present with start-stop system of the openness.

Similar performance as the current mps

The sports variant of the second generation of the mazda 3 comes with engine technology, which has already preserved in the process. Because already there is a 2.3-liter turbo gasoline with the designation of disi, which indicates the direct injection. According to mazda, however, the engine is now designed for euro 5 and consumes fewer fuel than before. Exact specifications are still missing, but it is expected that it remains with 260 hp. The "old" mazda 3 thus achieves a highest speed 250 km / h and requires 6.1 seconds for the sprint to 100 km / h.

From siss will be i-stop

The second novelty turns to a broader audience. The second.0 mzr disi, which is also offered in mazda 3, is a smaller variant of the 2.3-liter gasoline. The new engine will replace the current two-liter petrol engine with 150 hp. He should consume for twelve percent less than the transaction model. This helps a start-stop automatic, which mazda has been a bit bulky as siss. In series use, it will heat i-stop, which should probably indicate a "smart" start-stop system. In fact, i-stop is a riched system, because it is based on the idea of starting the engine through a targeted tongue process. This reboot should take only 0.35 seconds in practice.
