Chevy Silverado 4.3-liter EcoTec3 V6 nets 18 mpg city, 24 highway

There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.

This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado the highest towing rating among standard V6 models with a 7,200-pound towing capacity.

2014 Chevrolet Malibu is Roomier, More Efficient

Chevrolet recently unveiled the 2014 Malibu – a roomier, more refined and more efficient execution of its midsize sedan. Updated styling, a revised interior, a new 2.5L standard engine and suspension enhancements highlight the changes. It goes on sale this fall.

“The 2014 Chevrolet Malibu builds on the strengths established by the all-new 2013 Malibu to make it a stronger choice for customers,” said Mark Reuss, president, General Motors North America. “The midsize sedan segment is the most contested in the industry and we’re not sitting still with the 2014 Chevrolet Malibu.”

The new and enhanced features include:

• Revised front-end appearance
• Roomier rear seat with 1.25 inches (31.7 mm) more knee room
• Redesigned center console
• New 2.5L engine with variable valve lift control and start/stop technology helps deliver estimated fuel economy of 23 city / 35 highway – a 5-percent improvement in city mileage and 3-percent greater highway efficiency
• Nearly 14 percent more torque from the available 2.0L turbo engine – 295 lb-ft of torque (400 Nm) – engineered for a greater feeling of power on demand
• Suspension enhancements derived from the all-new 2014 Impala engineered to contribute to a more refined driving experience
• New available Side Blind Zone Alert and Rear Cross Traffic Alert safety features

Malibu’s revised front-end appearance is influenced by the all-new Impala, creating a more cohesive look across Chevrolet’s sedan lineup. The front fascia features a new, more prominent lower grille and the hood extends down and over the leading edge of a narrower upper grille. The grille openings – with black grille texture – are wider and accented with chrome.

Inside, redesigned seats contribute to greater rear-seat space and greater comfort. The front seatbacks are shaped to improve rear-seat knee room, while new cushion sculpturing and revised cushion material allow passengers to sit deeper in the rear seats. Approximately half an inch was trimmed from the front of the rear seat cushion, for greater comfort behind passengers’ legs.

The Malibu’s redesigned center console has a longer armrest designed for greater comfort, along with a pair of cup holders and dedicated storage for two cell phones.

“We made changes within 18 months, demonstrating an unprecedented commitment to make the Malibu the best car it can be,” said Ken Kelzer, executive chief engineer, global full-size and midsize cars. “The 2014 Malibu has been engineered to deliver more precise ride and handling that is on par with more expensive sports sedans.”

More efficient, powerful powertrains
An all-new Ecotec 2.5L Intake Valve Lift Control DOHC four-cylinder engine with direct injection is the 2014 Malibu’s standard engine. Its variable intake valve actuation enhances efficiency and helps lower emissions, while also enhancing low-rpm torque, for a greater feeling of power at lower speeds. When the iVLC system operates in low-lift mode, the engine pumps only the air it needs to meet the driver’s demand. The system switches to high-lift mode at higher speeds or under heavy loads, providing the full output capability of the engine.

New start/stop technology shuts down the 2.5L engine to save fuel when the Malibu stops momentarily, such as at stoplights, contributing to an estimated 5-percent increase in city fuel economy. The engine automatically starts again when the driver takes his or her foot off the brake. An auxiliary battery powers electric accessories such as the climate system, power windows and radio during engine restarts.

The new 2.5L is SAE-certified at 196 horsepower (145 kW) and 186 lb-ft of torque (253 Nm). Revised transmission shift points and quicker shifts also enhance the feeling of performance – while delivering greater refinement.

Additionally, the 2014 Malibu’s available 2.0L turbo engine delivers nearly 14 percent more torque than its predecessor. It is SAE-certified at 295 lb-ft (400 Nm). New engine calibration and tuning account for the improvement, making the Malibu 2.0L turbo’s torque the best in the segment, even among competing six-cylinder-engines. The result is a stronger feeling of acceleration from a stop and a greater feeling of power on demand in almost all driving conditions.

The 2.0L turbo also produces an SAE-certified 259 horsepower (193 kW). The Malibu ECO remains in the lineup and receives the exterior and interior upgrades as well as chassis and suspension updates.

Chassis refinements
Chassis and suspension updates inspired by the all-new 2014 Impala also contribute to the 2014 Malibu’s more refined driving experience, including rebound springs that are internal to the struts. They enable more refined calibration of the dampers for a smoother overall ride, while also improving body roll control and weight transfer during acceleration or turning. That helps keep the wheels planted, contributing to a more precise, controlled feel – especially while cornering.

Fuel-saving electric power rack-and-pinion variable-effort power steering is standard and enables nearly effortless low-speed maneuvers and a higher degree of steering feel at higher speeds. Revised, higher-effort calibrations for 2014 were engineered to improve the overall steering feel. Also, the Malibu’s brake system has been revised to provide a more confident feel.

Additional chassis control technologies include four-channel anti-lock brakes, full-function traction control, four-corner electronic stability control, electronic brake force distribution, brake assist system, corner brake control, hydraulic brake fade assist and drag torque control.

Enhanced safety
New Side Blind Zone Alert and Rear Cross Traffic Alert safety features are offered, and the Malibu also comes with 10 standard air bags and an available rearview camera system.

GM to offer 2 years free maintenance on most 2014 models

General Motors is offering most of its 2014 lineup with free maintenance. Since 2011, Cadillac models have all come with a four-year/50,000-mile complimentary maintenance program, but Chevrolet, Buick and GMC vehicles will now come standard with free maintenance for two years or 24,000 miles for the 2014 model year.

The program will give vehicle owners and lessees free oil changes, tire rotations and 27-point inspections following the recommended maintenance schedule laid out in each vehicle's owner's manual. We contacted GM to see which vehicles were eligible for the program, and a spokesperson got back to us with the following comment:

"All 2014 models are eligible, it's just that the included services vary by model, e.g., Spark EV would not need oil changes, Corvettes don't recommend tire rotations."

Even better, this plan applies to 2014 model year vehicles already purchased or leased, and it is fully transferable if the car is sold.
