Silently into the fast lane

Silently into the fast lane

While honing his Porsche Cayenne hybrid is already a Tesla competitor in 911-base work. The E-Ruf is not yet ready for production, weighs nearly two tons - and runs at least 225 cases.

What makes a real 911? The rear-wheel drive of course. And the six-cylinder boxer engine with its powerful babbling and the fantastic ride. At least six of you have to adopt in the future, well, if the E-Ruf A model is developed for mass production. Based on a Porsche 911, the tuner and car manufacturer presents call from Pfaffhausen an electric sports car, and shows how in Zuffenhausen might look like in the future.

The three-phase AC motor measures only 40.5 inches in diameter and sits in the engine compartment just behind the rear axle differential. Also, the electric 911 can therefore claim to being a real Hecktriebler. The engine delivers a maximum of 150 kilowatts (204 hp), torque of 650 Nm is available immediately after the launch. The Tesla Roadster would drive behind the Porsche at the moment anyway: The E-Ruf is to speed in about seven seconds from 0 to 100 km / h, the development objective is somewhat spongy "under seven seconds." The Tesla creates the sprint to 100 km / h in just under four seconds, but weighs 1.2 tonnes and well below the 1.9 tons of heavy e-reputation. A normal 911 takes about 1.5 tons on the scale - and him in a maximum of five seconds to 100 km /

The lion's share of the additional weight of course make the batteries from the E-Ruf 550 pounds drags it around with him. Engine and the front luggage compartment are completely besieged by batteries. The engine itself weighs only 91 kilograms. The maximum speed of the electric Porsche is located at 225 Km / h. "For the further development steps are still modifying" to expect befitting features, promises the car manufacturers. The electric Porsche has a gearbox with six gears. "In fact, it is probably enough to insert the sixth gear and drive off with the gas pedal," tells reputation and adds that it is in an electric car really more of a handle, "Ampère pedal."

An improvement in acceleration was possible if you choose one of the lower gears. "Of course one is so strong sprint capacity at the expense of the achievable range," restricts the automaker. The 96-Lithium ion batteries put together an energy reserve of 51 kWh available. "This represents the theoretical pure energy content of 5 liters of petrol and indicates the difficulty of storing" electricity, say the reputation of developers. The performance of spiral in the battery development interpret but sharply upward. When coasting, the motor generator and produces electrical energy with which the batteries are powered.

The stromernde 911, unlike the Tesla Roadster an experimental vehicle. "The prototype of the A-series is" still a significant distance from the fully developed car with electric drive, says the company reputation in a statement. The range of the E-Ruf model A lies at 250 to 320 kilometers. The life of the battery is charging cycles to the reputation of 3000 would be almost four times as much as the Tesla Roadster. During operation, the electronic monitors constantly the voltage and temperature in the battery cells in order to avoid overheating.

The idea for the electric Porsche is the company president Alois Ruf Jr.. been associated with its three hydropower plants, says the company. "The annual amount of energy from these power plants is about 35 million kWh of energy that would be necessary to a car like the E-Ruf 3500 times" to let go of the globe, the company estimates. "The whole thing is in the public network by the treaties of the energy for day or night current equivalent of € 2.50 to 5 per 100 kilometers," reads the statement of the automaker. lenovo thinkpad x41 battery

The company, established reputation in the Bavarian Pfaffhausen employs 65 staff. Reputation is not only Porsche tuner, but registered since 1982 as a vehicle manufacturer. The first model with its own telephone chassis number was the call of BTR with a 374-hp turbocharged engine.

The trunk has shrunk compared to the previous light, with 467 liters capacity, but remains high. The E-Class Mercedes for example, is content with 400 liters. The back seat for the C5 is also divided asymmetrically and can be folded down without much effort - this creates extra storage space when needed. The tailgate itself can be opened easily and far and also the opening is large enough dimensions. vgp-bpl8 battery

Angry however, the high sill, over which one must haul his bags or shopping only once. The felt fabric with which the boot is designed can be further bad clean. And here are a few small shelves would have been helpful. Under the boot floor hidden way to request a full spare tire.

The clarity from the driving position is not the best - making the body section of the C5. It looks good, what happened before one goes on the road, when parking but more by feel than by certainty. Beginning and end of the car can be guessed, the wide B-pillar also interfere. The electronic parking aid (€ 700 per packet) is therefore useful invested capital.

The four-cylinder diesel under the bonnet enough with its 100 kW/136 hp and a torque of 320 (in the boost mode, it briefly 340 Nm) is sufficient for the 1.7-ton truck quickly and swiftly through the traffic to . move The booster makes for brisk overtaking on country roads, overtaking on the highway at high speeds is not quite as crisp. The sprint from 0 to 100 km / h creates the C5 diesel with manual transmission in acceptable 10.6 seconds at 204 km / h is the maximum speed reached.

Over the whole range of motor runs quiet and cultured, the noise in the interior remains pleasantly quiet. When the C5 consumption shows more on average: Official 6.0 liters of diesel per 100 km are in the same order as in the test measured a good seven liters. The particulate filter is standard.

A highlight for the C5 is expected, the ride comfort. The hydropneumatic suspension muted hovers over all the bumps and keeps them away from the passengers. Only if the transverse joints or potholes are too violent, even more will not help the hydro-pneumatic. Adaptive Suspension controls depending on speed and road conditions also, the ground clearance of C5.

The chassis can move on tracks such as the Citroën its path, directional stability, even in critical situations kurvensicher and well controlled. The steering is precise, but gives little sense of the road. The 6-speed manual transmission flutscht without heel and on short routes through the scenery, the course itself are well adapted to the engine. All this makes for a relaxed feel.

For a base price of € 27 350 of the C5 with a 2.0-liter HDi Although no marked bargain, but in view of the extensive standard equipment a very fair deal. Are recommended from the options list, the Bi-Xenon Headlights (930 €) and the lane departure warning system that signals an overrun of the road marking without flashing gently awakening shock in the lower back (610 €). lenovo thinkpad t500 battery

Those who travel a lot, is expected to make friends with the 6-speed automatic (1500 €), which switches smoothly and precisely, making the cruise more enjoyable with the C5. The Citroën C5 is still one and thus a Frenchman. And that's good.

With the updated C5 to the French in Germany finally break into the business with a company car. The comparison does not shy away from the local middle class, the import from the neighboring country. vgp-bps2a battery

Where only the French healthy self-esteem is gone? Your C5, praise the recruiters of Citroen, was "as good as a German car, the middle class." And got to see in the TV spots, the British TV audience for a while, an Aryan-looking Blondling C5 slides over the dark streets, which suggest, if only for the black letter of the Ortswegweisern a fairly clear geographical and temporal mapping. vgp-bpl9 battery

Quite superfluous all this: who is with the C5, which has the first kilometers absolutely no doubt that the comfortable touring car is comparable to any German agents in their class. Citroen calculated to be able to advance thanks to this self-denial, finally succeed in the fleet of German managers floors. There traditionally dominated especially the Teutonic Trinity Mercedes, Audi and BMW.

Only by using the company car fleets are, however, by the calculus of the French still get the sales, which collapsed on the private market for a long time are no longer possible. But what stands in the way while the C5, the less likely to be his equal because of the technical qualities in these circles more conservative tastes. Individualists will love the Citroën design. On compliance and visibility drilled manager probably less serious.

You do not know what they are missing. Because of a C5-round balanced, high quality and very comfortable car has become, made with a lot of intelligent technology and quality. Sometimes a bit too much. Who in the comfortable driver's seat position is occupied, will feel immediately at home though - but at least when looking at the dashboard and steering wheel to the first sample set. Plenty of display instruments, it is because in the function and position to internalize. vgp-bps2 battery

And on the fixed steering wheel hub for Citroën kind he will find his way when driving under 20 switches. That can only look with - what shall prevent the switch in Daumenweite yes usually straight. Moreover, those things are so small that most still need to aim very carefully. And whether, in the split second of the two also need a lot of hits on small buttons of the horn may also be questioned.

Otherwise: The interior of the C5 is the best French cinema. With a balanced design, a pleasant blend of angular and curved elements plus high-quality materials that feel consistently good. The workmanship is very neat - even where the eye falls normally not the same. If you are used only once in the scheme of the abundance of these switches and knobs, the C5 can also be quite easy to use - much of it takes one from the electronics.

Thus, the parking brake when parking as when riding works automatically, daytime running lights as standard, the headlights are switched at the request of sensors and the steering wheel can be adjusted very individual. There is ample space for passengers. Front will also have people with more than 1.86 cm in height no problems. Pleasant abundant (more so in comparison to the German middle class) is also the great width, which ensures that the passenger is not kept clear. The seats are very comfortable and offer good lateral support. Even long journeys can be complete so without fatigue and dislocation of long legs. lenovo thinkpad t400s battery

Rear, the space just as comfortable for two adults - a third space is limited. The knee space is plentiful, the space above their heads is because of the sloping roof line for tall but somewhat narrow. What the front and rear painfully lacking is enough and sufficiently large bins.
