Brake better without brakes

Here is no brake to see, only the wheel hub engine. The total revolution in automobile construction does even not stop at the mechanical brake.

   Brake better without brakes Here is no brake to see, only the wheel hub engine. The total revolution in automobile construction does even not stop at the mechanical brake.









Everyone who made an emergency stop with ABS knows the coarse tugging of the control activities.

  Fast electronic instead of slowly mechanic


Instead of a mechanical slow ABS and ESC, it is possible to regulate the torque of the wheel hub engines much faster. So no brakes, all only be motor brake. 4 * 1000 Nm torque for braking.

  Long list


Gearing, clutch, differential for front and rear, differential for the axles, brake fluid, brakes, a long list what not to find anymore in a modern car.

Volvo Plug-in-Hybrid Volvo Plug-in-Hybrid
Finally expectation for a decent car for a strict ''No plug - no deal'' fan. It will take regretfully some years until it will be ready to order at a Volvo dealer.


IAA 2007 concept car from Volvo IAA 2007 concept car from Volvo
Concept cars are usually nice to look, but not decisively for the future. But it is different here. This here looks like a normal car in the Golf class.


Volvo wheelhub engine Volvo wheelhub engine
The revolution lets nothing like it was before. Gearing, clutch, differential for front and rear, differentials for the axles are yesterday.


Volvo wheel hub engines Volvo wheel hub engines
All the mechanical insufficiency from a 4 wheel drive replaced by 4 wheel hub engines. Complicate mechanic replaced by some electric cables.


Volov plug-in-hybrid battery Volov plug-in-hybrid battery
For about 100 km only electric driving is the battery below the luggage department. The battery can be charged extrem fast, because it must also deal with 500 kW from an emergency stop.


Volvo Plug-in-Hybrid Generator Volvo Plug-in-Hybrid Generator
What is the range of an electric car? As long as the carried generator delivers electric power. The engine has no mechanical contact to the wheels.

Opel Flextreme Plug-in-Hybrid Opel Flextreme Plug-in-Hybrid
55 km is the range of the Flextreme only with electric power. On longer distances produces a 1,3 litre Diesel engine with a 53 kW peak generator for the supply with electric power.


Tomorrow we will charge our cars like our mobiles Tomorrow we will charge our cars like our mobiles
On the IAA 2007 booth of Opel is near the Flextreme a couch and a desk with plugs to recharge mobiles. On the desk is written:


Criteria to purchase a car ready for the future Criteria to purchase a car ready for the future
At the Flextreme concept car without coachwork is to see the most important criteria to purchase a car in the future: The plug to recharge.


Flextreme chassis based on Opel Astra Flextreme chassis based on Opel Astra
Opel builts the Plug-in-Hybrid Flextreme with as much parts from the large serial construction. So the chassis is from the Opel Astra.


Serial Hybrid Opel Flextreme Serial Hybrid Opel Flextreme
The 1,3 litre Dieselengine with urea exhaust cleaning resides in the usual position, but it propels only a generator with 53 kW peak performance.


Opel Flextreme battery Opel Flextreme battery
The battery is listed with 16 kWh capacity. This sould be enough for 100km or even more. The range of only 55 km is an indicator


Urea tank for exhaust cleaning Urea tank for exhaust cleaning
The Opel Flextreme has left in the photo a 26 litre Diesel tank. In the smaller tank behind the battery is urea to reduce NOx nitric oxide in the exhaust gases.

PHEV Plug-in hybrid car. In the rear are the open Segway garage visivle.


Opel Flextreme without side mirrors Opel Flextreme without side mirrors
Because of the aerodynamic optimization, there are no more side mirrors. Instead of a side mirror are in the fron part of the front side window is a camera installed.

Below the luggage department is a garage for 2 Segway scooters. No, this is not a motorhome, this is a medium sized car.


Aerodynamic optimized rims Aerodynamic optimized rims
Who looks exactly will notice the transparent plastic at the large free spaces of the rim. Only the small free spaces let air to the disk brakes.


GM Chevrolet Volt GM Chevrolet Volt
The plug-in-hybrid Chevrolet Volt shows on the General Motors fair booth the other options for the generator: Petrol engine or hydrogen fuel cell instead of Diesel engine.


Chevrolet Volt gasoline Chevrolet Volt gasoline
The chevrolet Volt with a 3 cylinder turbo engine for the range extender. Because the generator is only used with high load, there is no advantage for the Diesel at small load.


Chevrolet Volt Motor Chevrolet Volt Motor
Is a Diesel engine at 30.000 km a year economical? Presently yes. At a plug-in-hybrid are the borders of economy moved towards the petrol engine.


Chevrolet Volt tanks Chevrolet Volt tanks
The petrol version has 2 tanks with 26 litres. Left is at the Diesel the exhaust pipe. Where at the Diesel is the urea tank, is here the battery longer.


Chevrolet Volt Plug-in hybrid hydrogen Chevrolet Volt Plug-in hybrid hydrogen
32 km range with the batteries and 480 km with the hydrogen tanks. Mankind will seriously stop the climate disaster. Fossile fuels are highly taxed.


Chevrolet Volt Plug-in hybrid with fuel cell Chevrolet Volt Plug-in hybrid with fuel cell
The plug-in hybrid drive concept makes the use of a fuel cell more easy. 32km range with the batteries alone, complete without fuel cell.


Hydrogen tank halfs place for batteries Hydrogen tank halfs place for batteries
The battery for the Chevrolet Volt hydrogen is only half as long as at the petrol version. The front hydrogen tank reduces the space away for the battery.


Maybe upgradeable with 4 wheel drive Maybe upgradeable with 4 wheel drive
At the hydrogen variant of the Chevrolet Volt is at each rear wheel a wheel hub engine. Maybe it's in the future possible to have four wheel drive as an upgrade?

Chevrolet Volt flat bottom Chevrolet Volt flat bottom
Most of todays cars look very aerodynamic above. But below very cleft. Not so Volt and Flextreme, they have both a flat bottom.


Because they do not know what they do Because they do not know what they do
Should the automobile industry do more for the climate protection? The result, only 1/3 Yes shows the insufficient enlightenment of the car drivers about our future cars.
