BANGKOK, THAILAND – The All-New Chevrolet Captiva SUV coming to Thailand in the second half of the year will benefit from General Motors’ engine rightsizing strategy to equip new models with smaller, more fuel-efficient engines that use turbochargers and other advanced technologies to provide plenty of horsepower and torque for driving enjoyment.

The All-New Captiva is powered by a new 1.5-liter turbocharged four-cylinder engine mated to an all-new continuously variable transmission (CVT) developed in conjunction with Bosch. While the turbocharger provides efficient performance and plenty of power, the CVT’s advanced system analyzes road conditions gathered from sensors to deliver smoother acceleration and deceleration across eight pre-determined step points to provide real driving satisfaction. Customers can choose from multiple driving modes, including Eco and Sport.

Captiva’s new-generation engine generates 143 hp (105 kW), enabled by the latest turbocharger from Honeywell. The turbo kicks in at just 1,000 rpm, boosting peak torque to 250 Nm (184 ft.-lb.) at 1,600 – 3,600 rpm and providing plenty of performance on demand. Delivering 250 Nm means Captiva is among the class leaders across the SUV C segment for torque, providing easy and confident overtaking when you need it and the ability to transport passengers and luggage with ease, no matter the driving
conditions. Captiva’s strong torque enables you to quickly gain speed and its smooth power will always keep you moving.

The engine employs a new highly-efficient combustion system that provides swift torque and robust
power throughout the drive. Its optimized air intake produces greater pressure and a higher compression ratio for better fuel economy. That means fewer stops to refuel.

In keeping with Captiva’s fighter jet-inspired styling, its engine uses a large quantity of aviation-grade materials such as high-strength, lightweight and heat-proof alloys. The reliability of the engine has been ensured by more than 10,000 hours of limit tests, deep thermal shock tests and 300,000 kilometers of
simulated lifecycle testing. In other words, drivers can look forward to getting a lot of “frequent flyer miles” with Captiva.

Engine Rightsizing – the Right Choice for the All-New Captiva

The All-New Captiva benefits from GM’s engine rightsizing strategy to equip lighter weight vehicles with smaller, turbocharged engines. The redesigned SUV weighs less than its 2.4L-powered predecessor – up to 200 kg lighter depending on 5- or 7-seat confirmation. In general, lighter weight vehicles require less power to do the same amount of work.

Turbocharging is one way GM boosts performance of smaller engines. GM has rapidly boosted its use of turbocharged engines on its vehicles around the world. In the U.S., GM’s turbo availability for passenger car gas engines has gone from 5 percent in 2010 to 49 percent in 2017.

A turbocharger’s on-demand performance is like having two engines in the same vehicle: one for fuel economy and one for power. Proper sizing of the turbocharger allows an engine to sip fuel under lighter driving conditions because the extra turbo power normally associated with a larger engine is held in reserve. Fuel savings can be realized when the vehicle is not driven aggressively when compared to a larger, non-turbocharged engine that produces similar peak power. Captiva is a perfect example; an efficient 1.5L engine providing among the highest torque figures in the segment thanks to advanced turbocharging technology.

The turbocharger’s performance-boosting advantage comes from forcing greater airflow into the engine. Its pressurized charge packs more air into the cylinders, allowing them to process the air and fuel normally associated with a larger engine for improved acceleration. The technology uses exhaust gases to power a turbine like fan, which drives a pump that blasts a denser mixture of air into the engine. This increases the engine’s output for greater driving satisfaction.

“Turbocharging is one of our most important technologies with lighter vehicles like the All-New Captiva to achieve great fuel economy. In most cases it enables us to make our engines smaller without sacrificing peak power to enable our customers to go farther,” said Mr.Chatchawan Chantaket, General Director of Product Engineering, GM Southeast Asia.
