The current xB was first released for the 2008 model year. At that time one of the upgrades from the prior version was the engine, along with a complete redesign. The 2.4L engine was already in use for the Camry sedans and Solara coupe models. So it is a well-proven engine from the Toyota stable.
The Scion philosophy is that all the cars leave the factory exactly the same with the exception of the transmission. The idea is that the buyer customizes their car at the time of purchase with a variety of accessories and added items.
As a result, there is only one engine choice in the 2010 Scion xB. At 2.4L this engine offers 158 horsepower and torque of 162 at 4400 rpm from four cylinders. The engine is also utilizing Toyota’s VVT-i technology. The variable valve timing with intelligence (VVT-i) uses a double overhead cam and 16 valves to optimize the airflow through the engine. This results in more power and the added benefit of better fuel economy. In line with the newer engines in the market, this requires no tune up until the mileage has exceeded 100,000, It has a sealed cooling system that is also rated as maintenance free for the first 100k.
As a second brand for the Toyota company, Scion has been successful at creating their own unique identity. Sharing engines that are considered bulletproof in conjunction with the unique and forward thinking designs of their line, Scion is a brand to be reckoned with. The fact that the 2.4L engine in the xB body offers an excellent power to weight ratio, will only take the Scion brand further along this road.
