With plans to introduce a new entry-level sports car, the next-generation Porsche Boxster will move up in size, following the likes of the BMW Z4. According to a report by Automobile, the next Boxster will grow by up to 2.5-inches between the wheels while overall length will expand by roughly 1.5-inches, improving ride quality and interior space. The architecture won’t be an adaptation of the current platform but an all new setup. The surprise, however, is that unlike the Z4′s significant weight gain, the Boxster will shed pounds, dropping roughly 35 lbs to just over 2,900 lbs.
Engine downsizing will also play an important role in Porsche’s Boxster plans with the base model switching from the current 2.9-liter to a 2.7-liter that will deliver more than the current 255-hp. When a mid-cycle update comes around in 2015, Porsche will look to phase out the 6-cylinder engines in favor of fours, with a new twin-turbo 2.5-liter making around 360-hp and 350 ft-lbs of torque.
The use of more efficient engines, as well as better aerodynamics and high-tech features like a start-stop system, regenerative braking and new electric power steering will add up to an 18 percent improvement in fuel economy.
Porsche is expected to debut the all-new Boxster at the Detroit Auto Show in 2012.
