Preliminary Specs on New Four-Cylinder Engine for 2009 Toyota Highlander

Toyota is introducing a new’s 2.7-liter inline four-cylinder engine in the Highlander mid-size sport utility vehicle (SUV) in January. (Earlier post.) The four-cylinder Highlander carries EPA fuel economy estimates of 27 mpg highway, 20 mpg city and 22 mpg combined. In addition, it will be EPA-rated as an Ultra Low Emission Vehicle (ULEVII).

The four-cylinder engine will generate 187 hp (139 kW) of power at 5,800 rpm and 186 lb-ft (252 Nm) of peak torque at 4,100 rpm on regular 87 octane fuel.

The engine is equipped with a variable intake manifold and dual variable valve timing with intelligence (VVT-i), which controls phasing of both the intake and exhaust camshafts to maximize fuel efficiency and torque. Both of these technologies help give the 2.7-liter engine a broad torque curve providing enhanced fuel efficiency, lower emissions and a strong response at all engine speeds. A dual exhaust manifold will also help achieve strong low-end torque and maximize power output.

The new engine will be mated to an all-new six-speed electronically- controlled automatic overdrive transmission with intelligence (ECT-i) that is one of the lightest and most compact in its class. The new transmission delivers a smooth shifting, remarkably quiet ride that is on par with a V6, according to Toyota, and quick acceleration for a four-cylinder.

Internal preliminary 0-60 mph testing was timed at 9.7 seconds, nearly one second quicker than the average four-cylinder mid-size SUV. When equipped with a tow package, the new powerplant will achieve a maximum towing capacity of 3,500 pounds.

With the new four-cylinder engine, Highlander will be the only mid-size SUV in the current market to offer three engine choices. The 3.5-liter Highlander V6 is available in two- and full-time four-wheel drive. The full-time 4WD-i Highlander Hybrid is equipped with a 3.3-liter V6 engine and front and rear electric motors.
