A honeycomb body includes at least a housing and a honeycomb structure with a multiplicity of channels. The honeycomb structure includes at least one at least partially structured metallic layer forming connecting points which fix the honeycomb structure. A cross section of the honeycomb structure has radial zones with connecting points. At least 1% and at most 20% of inner contact points of the at least one at least partially structured metallic layer in at least one of the zones forms a connecting point in the cross section. The channels have a different channel cross section in at least two of the radial zones. A motor vehicle having the honeycomb body is also provided.

1. A honeycomb body, comprising: a housing having a longitudinal axis and an inside diameter;a honeycomb structure disposed in said housing and having a cross section across said longitudinal axis with radial zones and at least one at least partially structured metallic layer having two terminal end
1. A honeycomb body, comprising: a housing having a longitudinal axis and an inside diameter;a honeycomb structure disposed in said housing and having a cross section across said longitudinal axis with radial zones and at least one at least partially structured metallic layer having two terminal ends, both of said terminal ends bearing against said inside diameter of said housing;said at least one at least partially structured metallic layer having inner contact points and defining a multiplicity of channels;at least 1% and at most 20% of said inner contact points in said cross section in at least one of said radial zones forming a respective connecting point fixing said honeycomb structure, said connecting points having a density, as viewed along said at least one at least partially structured metallic layer, being higher in one of said radial zones than in at least one other of said radial zones; andsaid channels having different channel cross sections in at least two of said radial zones. 2. The honeycomb body according to claim 1, wherein said inner contact points have a higher density per unit of cross-sectional area of said honeycomb structure in one of said radial zones than in at least one other of said radial zones. 3. The honeycomb body according to claim 1, wherein said at least one at least partially structured metallic layer has a different profile in one of said radial zones than in at least one other of said radial zones. 4. The honeycomb body according to claim 1, which further comprises projections projecting into said channels in one of said radial zones and influencing a cross section of said channels. 5. The honeycomb body according to claim 1, wherein said at least one at least partially structured metallic layer has a structure with a different width or height in one of said radial zones influencing a cross section of said channels. 6. The honeycomb body according to claim 1, wherein said connecting points are formed with an extent in a circumferential direction of said honeycomb structure in one of said radial zones. 7. The honeycomb body according to claim 1, wherein said honeycomb structure is formed with a coating in at least one of said radial zones. 8. The honeycomb body according to claim 1, wherein said at least one at least partially structured metallic layer includes a multiplicity of at least partially structured metallic layers, both of said ends of all of said multiplicity of at least partially structured metallic layers bearing against said housing and being connected to said housing to a limited extent axially. 9. A motor vehicle, comprising: an internal combustion engine; andan exhaust-gas aftertreatment system, said exhaust-gas aftertreatment system having at least one honeycomb body according to claim 1. 10. The honeycomb body according to claim 1, wherein said at least one at least partially structured metallic layer has a profile being one of an S-shape, V-shape, W-shape, or U-shape. 11. A honeycomb body, comprising: a housing having an inside diameter;a honeycomb structure disposed in said housing and having a cross section with radial zones and at least one at least partially structured metallic layer, said at least one at least partially structured metallic layer passing between at least two of said radial zones and having two terminal ends, both of said terminal ends bearing against said inside diameter of said housing;said at least one at least partially structured metallic layer having inner contact points and defining a multiplicity of channels;at least 1% and at most 20% of said inner contact points in said cross section in at least one of said radial zones forming a respective connecting point fixing said honeycomb structure, said connecting points having a density, as viewed along said at least one at least partially structured metallic layer, being higher in one of said radial zones than in at least one other of said radial zones; andsaid channels having different channel cross sections in at least two of said radial zones. 12. The honeycomb body according to claim 11, wherein said at least one at least partially structured metallic layer has a profile being one of an S-shape, V-shape, W-shape, or U-shape.
