Lexus is introducing its first ever turbocharged engine

Lexus was missing turbo charging on the road and the area is mainly dominated by higher end European suppliers like Saab and Volvo. If Lexus wants to be compete with its rivals such as Audi, BMW, Mercedes-Benz and Buick they need to incorporate turbocharging very soon.

The 2015 Lexus NX 200t will be the first model to host turbochargers in Lexus models. As the marquee’s first venture into petrol turbocharging, the NX and its 2.0-litre turbocharged four-cylinder Lexus engine will be the first ones.

At its heart, the 2.0-litre twin-scroll turbocharged four-cylinder engine was designed with 10.0:1 compression ratio and an additional 17 pounds from turbocharger developed by Toyota Engines division. There’s an equilibrium tube to put down harshness and shaking, controlled by resin gears.

A highest of 235 horsepower is generated at 5,600 rpm. Torque comes in at a comparatively vigorous 258 pound-feet from 1650 to 4,000 rpm. Premium grade fuel is required, and Lexus estimates the new engine will turn out 22 mpg in the city, 28mpg on the motorway and 24mpg combined but if you opt for an all wheel drive version then in-city fuel economy will be dropped by 1mpg, furthermore it is paired with a six-speed automatic transmission.

Lexus has introduced a bit of new-think technology into its first ever turbo engine, starting with the cylinder head, which boasts water cooling and is pooled with an incorporated exhaust manifold of four-into-two to bring the turbocharger near to the intake induction system and to divide the engine’s exhaust into two that feed into the twin-scroll turbo. In the same way, the liquid-cooled intercooler is a vital part of the engine. Finally, a variable waste gate valve improves effectiveness with enhanced efficiency.
