It runs Android Kit Kat on a 2.3GHz Snapdragon 800 processor and 450MHz Adreno 330 GPU and has 2GB RAM, and features an 8-megapixel rear camera and 1.3-megapixel snapper on the front, as well as new photo tools."The advanced new lens on Nexus 5 captures more light for brighter night and sharper action shots," said Sundar Pichai, vice president of Android.
The 16GB version is £299 and the 32GB version is £339 - both are SIM free without a contract, but are also available on contract from Three and O2.
The Nexus 5 is available to order in the UK immediately, but will currently take a week to ship from Google Play.
It has a Full HD resolution, resulting in a pixel density of 441ppi and it has Corning Gorilla Glass 4 protection.
The Google Pixel XL has a Quad HD resolution across its 5.5-inch display, meaning a slightly higher pixel density of 534ppi.
A new HDR mode automatically snaps a rapid burst of photos and combines them to give you the best possible single shot."For connectivity, it features dual-band 802.11abgnac Wi-Fi, Bluetooth 4, NFC and 4G/LTE.
Google promises the 2,300m Ah battery will offer 17 hours of talk time, and the Nexus 5 supports wireless charging.
The Nexus 5X is, thankfully, an exception to that rule, starting you off at 9 for the 16 GB version, and 9 for the 32-gigger.
In Europe, however, the price might be quite a bit more inflated, at € 479 for the 16 GB version, while the 32 GB model will net you €529.
Importantly, Nexus was a chance for Google to say "this is what Android is". The biggest change is a shift from the Nexus programme entirely and into Pixel.
