Toyota Rolls Out the New Camry and Camry Hybrid
9 January 2006
|The new Camry Hybrid|
Toyota introduced the redesigned sixth-generation 2007 Camry, including the new hybrid version, at the Detroit auto show, beginning what Senior Vice President of Automotive Operations Don Esmond called “the biggest launch we’ve had in our nearly 50 years of existence.”
In completely redesigning the Camry—the best-selling car in the US for eight of the last nine years—Toyota engineers opted for enhanced performance and style, shooting for a athletic, energetic image. Camry buyers, Toyota executives explained, felt that the car was too “ordinary.”
The new baseline engine is an enhanced version of the older 2.4-liter four-cylinder engine. The redesign includes optimized intake and exhaust systems, as well as reduced internal friction and enhanced engine-block/crankcase rigidity to improve fuel economy and reduce noise and vibration. Power output has very incrementally increased to 158 hp (118 kW) from 154 hp (115 kW), and torque to 218 Nm from 217 Nm, while maintaining the 24 mpg city/34 mpg highway (28 mpg combined) rating of the 2006 Camry.
For the new, high-end SE Camry, Toyota introduced a 3.5-liter, 268 hp (200 kW), 336 Nm V6, designed to deliver up to 40% better acceleration than the 2006 model year 3.3-liter V6. Dual camshafts in the 3.5-liter engine employ dual variable valve timing with intelligence (Dual VVT-i) for optimal cam timing and maximum power production at all rpm levels.
The high-end engine is coupled with an all-new six-speed automatic transmission that uses 21% fewer parts than its 5-speed predecessor.
Estimated fuel economy with the new powertrain is 22 city, 31 highway (25.3 mpg combined)—a 5% improvement over the 24 mpg combined of the 3.3-liter 2006 Camry while delivering 28% more power.

The Camry Hybrid uses a lower-power (147 hp/110 kW), lower-torque (187 Nm) 2.4-liter Atkinson-cycle engine coupled to a continuously variable transmission. The second half of this newest version of the Hybrid Synergy Drive is a 105-kw electric motor with 199 lb-ft of torque, an ultra-small inverter with a specially designed compact battery, and a transaxle. The hybrid uses a 244.8-volt NiMH battery pack.
The result is a combined 192 hp (143 kW) from the hybrid system with 275 Nm of torque, with estimated fuel economy for the hybrid of 43 mpg US city, 37 mpg US highway (40 mpg US combined).
Toyota expects to have the non-hybrid Camrys in showrooms in March, with the Camry Hybrid to follow several months later.
