Yo-crossover - to reinvent the wheel
On Dmitrov was a prototype of the first generation of the first serial hybrid Russian assembly - E crossover. The car is designed from the ground up and has in its structure a number of innovative solutions. In particular, the hybrid propulsion system and all-wheel drive transmission with two mechatronic modules. Also of note is that all the body panels of the car are made of plastic.
But frankly speaking, the prototype in a way to show the public can not, he is too "crude" and can cause a wave of bad press. The only thing that may be presented prototypes - to move under its own power, but the fact that they did it easily and comfortably take time.
In the meantime, a ride on what is. Go!
A huge interest in the new product, and so the company decided to take a risky move - to show the public a prototype of the first generation, which is usually a purely domestic product, in any case not being demonstrated in public. But any journalist only give a reason - just to be a lot of negativity. Therefore, a public demonstration of the prototype should be considered as the company's attempt to remind ourselves that, well, we're alive and well and razbotka is in full swing. After all, we know that a lot of Russians believe in the commercial success of the project e-cars.
It is a full serial hybrid, wherein the internal combustion engine that runs on gasoline or natural gas has no connection with the wheels. As the power unit is used vosmiklapanny engine FIAT of 1, 4 liters and 75 horsepower. It is connected to a generator, from which the energy generated comes from supercapacitors and electric motors on the front and rear axle.
The subframe and front suspension. Used classic McPherson with triangular links below. Mechatronic module integrating a motor, a reducer, a mechanical differential, the cooling system and a control unit located at the center thereof are located on the two drive shafts each wheel. Mechatronic modules are proprietary company.
The car body is composed of two structural elements: a steel supporting framework and the plastic body panels.
By linking the passenger compartment turn spacious enough for its class. Even when fully retracted back front seat, the rear can accommodate almost touching his knees in front of passenger backrest. Steering wheel reach, alas, is not regulated, and the range of adjustment of height is extremely small and can be reduced to two propositions: "lying on his knees," and "a little higher". And as a regular flight steering proved sufficient to correct the landing, but the slope of the steering would like less.
Under the flat floor is a supercapacitor unit is capacitors, which may briefly accumulate and release tremendous amounts of energy.
The bottom of the vehicle substantially equal, the center tunnel for an exhaust pipe of the internal combustion engine. The car has a solid clearance of 21 cm.
Rear Suspension - an ordinary beam. In the center as well as a front mounted mechatronic module.
The chassis have been the object of attention from journalists - they have learned all the length and breadth, especially actively crawling on the floor and studying how the car looks from below.
In the trunk of the car can be optionally installed cylinders for natural gas (methane). In this case, the owner should forget about the existence of the trunk, but the total stock of the progress of the car will increase to 800 kilometers (interesting mathematics, declared consumption under 5 liters per 100 km, but with such a power reserve is obtained that the flow rate is 10 liters). Traditional fuel tank 40 liters under the rear seats.
Let us again in the engine compartment (view from the left front fender). Left docked internal combustion engine with an electric generator. Bottom right - mechatronic module. Orange - high-voltage wires. high-voltage switching unit is located under the floor at the feet of the driver.
The stated capacity powerplant - 163 hp (120 kW), is achieved only when it is fully charged supercapacitors and transient. When discharged batteries power is limited capabilities of the petrol motor, plus the loss of energy conversion.
The two-color body is a little more than full of plastic. Pay attention to the clearance of the door panels. Honestly, I can not imagine how this will fight, because the door is also made of plastic, which can be easily bent.
In this case, the dark elements of the relief structure are almost "under carbon", which certainly will appeal to fans of tuning.
At the mercy of journalists given 5 cars and built two makeshift track. The heat from time to time incidents occurred - mechatronic modules overheated cars and refused to go normally.
The feeling of acceleration is very strange. When you start from a place on the charged supercapacitors felt good spurt that lasts literally for 3-4 seconds, then start up a gasoline engine and spins up to the cut-off, trying to charge the supercapacitors. All this time the car accelerates very sluggish.
Salon filled with the deafening roar of the engine, the driver releases the gas pedal reflex to stop the noise, the engine continues to flail at extreme speeds. The reaction to the gas pedal is zero.
In fact, the maximum acceleration, you can only get all the rest of the time for a few seconds have to accept the fact that less than 75 horses running under the hood, which can not make the crossover in any way accelerate. The maximum vehicle speed of 130 kilometers per hour.
It is obvious that the software requires a long fine-tuning of the engine algorithms internal combustion engine and mechatronic modules. Prospects there.
But I liked the control. I expected vague steering, suspension lax, undisciplined, but e-crossovers despite solid clearance in 21 centimeter rulyatsya very well. Contribute to the discomfort of making the rear beam on the bumpy road, but feedback on the steering wheel with electric power is excellent. Roll in corners for a crossover rather moderate.
Funeral in such form as he is now - not the final version. It will be further developed.
In total there are three displays (two color and one monochrome), the largest has a touch-sensitive controls and an excellent high-definition graphics. It uses the Android operating system.
Planting comfortable, I enjoyed it here. Notice the small lever on the right above the steering column - it switches the movement modes: D, N, R. parking, but there are the hand brake activated by the button on the left under the steering wheel. What exactly is it blocks I did not understand.
In the second row is spacious, but the windows on the rear doors do not fall down, you can only open up like a window. And yet, this ridiculous arm-holder on the left. He is attached to the driver's seat and has two positions - either it armrest for the driver, or the cup holder for the rear passengers.
What is the engine compartment of the prototype. There are two uncertainties remain. Mechatronic modules and supercapacitors frosts in principle are not afraid, but because apart from these people supposed to be transported in a car. In the summer they want cool and warm in winter. Mechanical air-conditioning compressor driven by a gasoline engine - means in the heat engine will always zavedon ( "chip" hybrid powertrain that, in the city and traffic jams you're standing still with the engine drowned). In winter, passengers will want to heat and petrol motors again have to work constantly to heat the cabin.
With the optional gas cylinders in the trunk of the car will not be at all. And most importantly - is not dependent on the presence of balloons in the car there was no room for a spare wheel. The developers say that the RV will be installed special self-healing after a puncture. A controversial decision for Russia, where the direction of prevailing over the roads.
The first batch of 10 thousand cars is planned to produce in 2015, and the design capacity of 40 thousand cars per year, the plant should be out in 2018.
According to the dimensions of the car as close to the Renault Duster. Vehicle curb weight of 1350 kg. Braking occurs mainly due to switching of electric motors in power generation mode. Feedback on the brake pedal because of this smeared. Those who went to the Toyota Prius, will understand what is at stake.
a special opportunity to experience the all-wheel drive transmission has not been on the steep turns the car slides out all 4 wheels, and shows a stable neutral understeer. The instructor sitting next, though noted that while it is not necessary so to scoff at the prototype.
What is the result? The feel of the prototype rather ambiguous. On the one hand it is extremely commendable that the company has decided to show the public how innovation is a process of vehicle development. But on the other side of the problem lies in the fact that the technical solutions used quite controversial and it is not clear whether the cost-invent the wheel? Can you just make a quality car with a conventional power plant?
Also, a big question is the price of the car. Company representatives did not give even indicative prices fork, so you and I can only speculate on the future price of Russia's first hybrid. How much it will cost: Available 500 000 or at least 1 million rubles? Are you ready to buy Yo-crossover?
