Tesla has given Roadster electric sports car a few upgrades. Rather than just giving the Roadster a new model year designation like a regular automaker does, Tesla is--true to its Silicon Valley roots--referring to the changes as a version 2.5 update.
Take a look at the new 2.5 version of the Tesla Roadster Sport from the rear quarter and you'll be hard pressed to notice any changes.
The car's rear diffuser also has been revised. However, Tesla revised it mostly to improve the Roadster's appearance and not its aerodynamics. If you look closely, you'll notice it has the newly available rearview camera.
The EV can be had in either of two variants: the Roadster and the Roadster Sport. The Roadster's estimated maximum driving range is 250 miles regardless of configuration and it has a 3.5-hour charging cycle when using the high-power connection.
Tesla now has an optional double-DIN receiver available on the Roadster. The unit is supplied by Alpine with the model number IVA-NAV-10. Upon closer inspection, it appears to be an OEM rebranding of the INA-W900 retail model. Look for a full review of this unit in the coming days.
As part of the technology package, the Roadster's standard four-speaker audio system is upgraded with the inclusion of a pair of door-mounted tweeters and a 6.5-inch subwoofer that is located in the rocker panel behind the driver. With about 300 watts of amplification, this is a marked improvement over previous Roadsters.
It doesn't appear as if Tesla changed the instrumentation panel on the 2.5 as it retains the Roadster's simple two-dial configuration. On the left is the speedometer and on the right is a power meter that indicates how much energy you're expending or regenerating.
At the base of the center stack is this touch-screen display that lets you monitor the status of the Roadster's various systems and create a driver PIN for additional security or to keep valets from having too much fun with your $100,000 investment.
