Volkswagen hopes a face-lift will halt sliding sales of the New Beetle in Europe and the US.
The retro model goes on sale this summer with its first freshening since the car debuted in 1998.
The New Beetle's styling changes are subtle. The front and rear fascia, fenders and side sills are new. Front and rear lights are slightly changed.
Inside the car gets chrome trim around the air vents and the instrument cluster.
VW is dropping the New Beetle's 2.3-liter, five-cylinder and 1.8-liter turbocharged gasoline engines in Europe because of low sales.
The 1.9-liter diesel engine has its horsepower raised to 105hp from 100hp. The 1.4-, 1.6- and 2.0-liter gasoline engines are unchanged.
In the US, the New Beetle will be offered with a 2.5-liter, 150hp gasoline five-cylinder powerplant only. Previously US buyers could choose models with 2.0- and 1.8-liter gasoline engines.
The New Beetle and its convertible derivative go on sale in the US in August, the same time as the first models are delivered to European car buyers.
The US is the New Beetle's largest market. Sales there for the first five months were 14,271 units, down from 17,963 in the same period last year, according the Automotive News Data Center.
Western European sales were 12,398 in the first five months, compared with 16,327 in the same period in 2004, according to market research JATO Dynamics.
