The Senna’s standard spec is intended to save weight. If you want an audio system, air conditioning or even Bluetooth connectivity for your phone, you have to add them as options. Some of those options don’t cost anything, but the Bowers & Wilkins seven-speaker audio system costs £5500; and, because our test car didn’t have it, we can’t comment on its quality.
The portrait-oriented infotainment remains a challenge at first, but you become used to negotiating its menu structures with practice. The Senna does get Mclaren’s factory navigation system, although it remains a little bit unintuitive to programme and doesn’t always suggest the best route. Smartphone mirroring isn’t possible.
Mclaren’s Track Telemetry app is an optional feature but ought to be on every Senna. It relays and records much more data than rival systems, from throttle position to tyre temperature to brake pedal pressure, and records and relays video from three cameras around the car to be enjoyed later.
