2007, developing and and channeled through a 4T65-E four-speed automatic with Tap-Up/Tap-Down shifting, sport suspension with tower-to-tower brace, 18" alloy wheels, universal home remote transmitter, rear spoiler and hydraulic power steering. Changes to differentiate the SS from the lower trims include three-spoke, leather wrapped steering wheel with SS badge, sport cloth and leather seats, side skirts, chrome tip exhausts, and more aggressive front and rear clips. Seventh generation (2008) The Malibu was extensively redesigned and re-engineered for model year 2008, with styling by Bryan Nesbitt. GM Vice Chairman Robert Lutz was determined to make the nameplate competitive with Japanese mid-size cars. Trim levels were base (2008 only), LS, LT, Hybrid (2008 and 2009 only), and LTZ. The LTZ trim had clear brake light lenses with red LEDs, the balance of trim packages retaining red lenses with conventional brake lights. The seventh generation Malibu uses a variant of the long-wheelbase Epsilon platform shared with the Saturn Aura, the Opel Signum, and Pontiac G6. It is assembled in Kansas City, Kansas. Overall, it is three inches (76 mm) longer, with a six inches (152 mm) longer wheelbase. Interior room remains mid-size, like the previous Malibus, and has been decreased from to , despite having a longer wheelbase, although front legroom has increased from to . Rear legroom has decreased from to . The interior design was revised, with a selection of two-tone color combinations (brick and tan two-tone), telescoping steering wheel, higher-quality materials and a twin-cowl dash design. Drag (Cd) is at 0.33 for the LTZ. Powertrain The seventh generation Malibu offered these engine choices: The 2.4 L I4 and 3.6 L V6 engine have aluminum blocks and heads, dual overhead cams, four valves per cylinder, twin balance shafts, and variable valve timing. The 3.5 L V6 has aluminum heads, an iron block, overhead valves, and limited variable valve timing. The 3.5 L V6 was offered as an upgrade for special-order fleet vehicles, to replace the Ecotec engine, and generally was not available for retail customers. The 3.5 L V6 was not available in the LTZ. The 3.5 L V6 with four-speed transmission has been the only drivetrain available in the 2008, 2009, and 2010 models in Israel. Partway through the 2008 model year, the 2.4 L Ecotec was offered with a six-speed automatic transmission to improve performance and fuel economy. For 2009 models, the six-speed transmission mated to the 2.4 L
