Buen día Salnhack, te paso un select para probar

SELECT C.IDCARRO, C.NOCARRO, C.INDICECONS, SUM(DHR.KMRECORRIDO), SUM(CO.CONSUMO)
FROM CARRO C INNER JOIN HOJARUTA HR ON HR.IDCARRO = C.IDCARRO
INNER JOIN DESCHOJARUTA DHR ON DHR.IDHOJARUTA = HR.IDHOJARUTA
INNER JOIN CONSUMO CO ON CO.IDCARRO = C.IDCARRO
WHERE CO.FECHA BETWEEN :FECHA1 AND :FECHA2
GROUP BY C.IDCARRO, C.NOCARRO, C.INDICECONS
ORDER BY C.IDCARRO

Saludos...
