1. The Altima, Nissan's biggest volume vehicle, is likely to come with a new sports model when it is redesigned for the 2007 model year. Target sales for the next-generation Altima are 250,000 to 300,000 annually. Sales this year through October are flat, at 171,875. 2. The 2006 Sentra compact may come with two to three new derivatives, which could include a hybrid to fight the Toyota Prius and a small SUV to fight Toyota's RAV4 and Honda's CR-V. The entry-level Sentra will not be geared toward the youth market, he says, but more toward an older conventional consumer. 3. Smaller crossover vehicles for both Nissan and Infiniti divisions. 4. Medium- and heavy-duty trucks, but only after proving the company can be competitive with full-sized light trucks.
