Major rivals of Lexus are Mercedes-Benz, BMW and Volvo. Lexus IS 250C is designed in a way that it performs at the finest level with the hi-tech aerodynamics and the power train. We may conclude that Volvo C70 is a more comfortable car with plenty of space for the rear passengers and cargo, but Lexus IS250c possesses high performance level. Both convertibles are available at almost same prices, but Lexus is a bit cheaper than the other. We have found difference among engine power of both the cars. Volvo has been installed with the engine of 227hp, while that of Lexus is 204hp. There is a slight difference between the fuel economy of Volvo and Lexus.
