A dual clutch transmission comprises first and second clutches 201, 202 having concentric output shafts 203, 204 which drive via, for example, bevel gears 205, 206, 207, 208 primary input shafts 220, 230 having axes of rotation perpendicular to axes of rotation of the clutch output shafts 203, 204. Primary input shaft 220 is associated with odd gears and comprises fixed gears 223-226 meshed with gears 263, 264, 273, 274 selectably mounted, via synchromesh clutches 265, 275, on layshafts 260, 270. Primary input shaft 230 is associated with even/reverse gears and comprises fixed gears 233, 234 meshed with gears 243, 244, 253, 254 selectably mounted, via synchromesh clutches 245, 255, on layshafts 240, 250. Layshafts 240, 250, 260, 270, have output pinions 246, 256, 266, 276 which mesh with output pinions 294, 295 that drive a differential 293. This configuration provides a dual clutch transmission with compact packaging since an overall length of the transmission with respect to the longitudinal input axis is reduced. Electric motors may be provided to create a hybrid power transmission.
