The more powerful V8 engine is the biggest news. It’s still not a Hemi, but the 4.7-liter V8 sports twin spark plugs (the only non-Hemi with that feature), higher compression and other tricks to bump power to 290 horses and 320 lb.-ft. of torque, improvements of 25 and 10 percent, respectively. The new engine is also more refined and offers better fuel economy as added bonuses. It’s also capable of running on E85 ethanol, in case you’ve got access to the stuff. A six-speed manual is standard with both engines. The V6 has an optional four-speed automatic and the V8 a new six-speed automatic. Both engines come standard with remote starting for 2008.
