The 2009 Chevrolet Impala 2LT upgrades the drivetrain of the LS and LT trims with a 3.9-liter V6 engine with 233 horsepower and 240 lb-ft of torque. Mated with Chevy’s four-speed automatic transmission with overdrive, this front-wheel-drive vehicle gets 17 city /27 highway mpg. Chevy’s StabiliTrak Electronic Stability Control System is standard.
The interior and exterior features of the 2LT add to the foundation of the LS and LT, and its additions include dual stainless steel exhaust, a rear spoiler, fog lamps, 17-inch machined aluminum wheels, Bluetooth, a leather-wrapped steering wheel with audio controls, and a flip-and-fold-flat rear seat.
The 2009 Chevrolet Impala LS is the base trim for this model, but it offers plenty for an entry-level vehicle. The drivetrain is a 3.5-liter V6 with 211 hp and 214 lb-ft of torque mated to a four-speed automatic transmission with overdrive that gets 19 city/29 highway mpg. The LS shares safety features with all trim levels, including traction control, dual-stage frontal and side-impact thorax airbags, four-wheel antilock disc brakes, and a tire pressure monitor.
The LS's exterior features 16-inch steel wheels, body-color rocker moldings and mirrors, and two-sided galvanized-steel body panels. The interior highlights include cruise control, a six-speaker audio system with auxiliary input jack, six-way power driver’s seat, dual-zone climate control, tilt steering wheel, anti-theft system, wood grain accents, and illuminated vanity mirrors.
The 2009 Chevrolet Impala LT shares a drivetrain with the base LS trim and builds off the interior and exterior features of that entry-level trim. The upgrades include 16-inch, five-spoke cast aluminum wheels, remote start, carpeted floor mats, deluxe instrumentation, OnStar with available turn-by-turn navigation, and an available luxury edition package that includes a power sunroof and a cargo net.
The 2009 Chevrolet Impala LTZ shares a drivetrain with the 2LT (a 3.7-liter V6 and a four-speed automatic with overdrive), but adds significantly everywhere else. The ride is improved with a performance-tuned suspension. The exterior gets 18-inch machined aluminum wheels, bright chrome door handles, and heated and power mirrors. The interior upgrades feature an eight-way power driver's and six-way power passenger front seat, a universal home remote, Bose sound system, leather-appointed seats, and an electrochromic, automatic-dimming rearview mirror.
The 2009 Chevrolet Impala SS is the powerhouse of this model lineup, packing a 5.3-liter V8 with active fuel management under the hood and capable of 303 horses at 5,600 rpm and 323 lb-ft of torque at 4,000 rpm. The V8 is mated to a heavy-duty four-speed electronically controlled automatic transmission and gets 16 city/24 highway mpg.
This performance-driven powertrain is the main reason for the increased pricetag of the SS - $31,135 MSRP, compared to $29,630 for the LTZ. Other than techno-metallic accents on the interior, the SS shares all the features of the LTZ, which builds off all the lower-priced Impala trims. The highlights include body-color rocker moldings and heated power mirrors, two-sided galvanized-steel body panels, remote start, OnStar, a rear spoiler, dual exhaust, foglamps, Bluetooth, and a Bose Sound system.
