Abstract

The invention relates to a motor vehicle, comprising a body and a drive train, wherein the drive train comprises a front axle (10), a rear axle (13), a drive unit, and a gearbox (20), wherein the drive unit is designed as a hybrid drive having an internal combustion engine (16) and at least one electric machine (17, 18, 19), wherein the internal combustion engine (16) can be supplied with fuel from at least one fuel tank (21), and wherein the or each electric machine (17, 18, 19) can be supplied with electrical energy from at least one electrical energy store (22) in motorized operation, and wherein the or each fuel tank (21) and the or each electrical energy store (22) are positioned in a common section (23) of the body.

Claims

1. A motor vehicle, comprising a body and a drive train, wherein the drive train comprises a front axle, a rear axle, a drive unit and a transmission, wherein the drive unit is designed as a hybrid drive with an internal combustion engine and at least one electric machine, wherein the internal combustion engine is suppliable with fuel from at least one fuel tank, and wherein the or each electric machine is suppliable with electric energy from at least one electric energy accumulator in the motor mode, characterized in that the or each fuel tank (21) and the or each electric energy accumulator (22) are positioned in a common section (23) of the body.

2. The motor vehicle as claimed in claim 1, characterized in that the common section (23) of the body, in which the or each fuel tank (21) and the or each electric energy accumulator (22) are positioned, is positioned in the vicinity of a center of gravity (25) of the motor vehicle.

3. The motor vehicle as claimed in claim 2, characterized in that the center of gravity (25) of the motor vehicle drops into the common section (23) of the body, in which the or each fuel tank (21) and the or each electric energy accumulator (22) are positioned.

4. The motor vehicle as claimed in one of claims 1 to 3, characterized in that the internal combustion engine (16) is arranged in a mid-engine arrangement to the rear of the front axle (10) and in front of the rear axle (13) and to the rear of the common section (23) of the body, in which the or each fuel tank (21) and the or each electric energy accumulator (22) are positioned.

5. The motor vehicle as claimed in one of claims 1 to 4, characterized in that at least one electric machine (18, 19) is assigned to the front axle (10).

6. The motor vehicle as claimed in one of claims 1 to 5, characterized in that at least one electric machine (17) is assigned to the rear axle (13).

7. The motor vehicle as claimed in one of claims 1 to 6, characterized in that the or each fuel tank (21) and the or each electric energy accumulator (22) are jointly coolable.

8. The motor vehicle as claimed in one of claims 1 to 7, characterized in that the or each fuel tank (21) and the or each electric energy accumulator (22) are positioned as a unit of modular construction in the common section (23) of the body.

9. The motor vehicle as claimed in one of claims 1 to 8, characterized in that the or each electric energy accumulator (22) is designed as a flywheel accumulator.
