Cadillac's performance-oriented SRX crossover becomes more affordable but just as sporty and lavish inside with a complete redesign. The SRX's newly standard direct-injection V6 provides improved fuel economy, while the turbocharged engine that arrives later in the model year promises to maintain the model's enthusiast appeal. And for families, the SRX now offers a new hard-drive entertainment system. It all comes back to price, though; with a base price in the mid-thirties, the base-model 2010 SRX is a luxury crossover bargain.
