Gordon Murray’s T.27 EV: official details, photos and specs

Article by Christian Andrei, on June 28, 2011

Gordon Murray Design unveiled its T.27 model, which is its latest ultra compact urban vehicle and the most efficient electric car in the world. The design and development of this £9 million program took only 17 months, including the time spent for the new electric powertrain produced by Zytek Automotive Ltd, which is one of the Consortium partners.

Financing for the project was made possible through the £4.5 million investment from the government-backed Technology Strategy Board.

With the unique, holistic, manufacturing process (‘iStream’) developed by Gordon Murray Design (the consortium lead partner), the T.27 is manufactured specifically for the city environment, reducing lifecycle impacts and enabling efficient, low-cost manufacture within the United Kingdom.

This vehicle model creates new standards in efficiency, packaging, safety, compact car dynamics, footprint and weight while answering issues on full lifecycle CO2 emissions, low cost motoring, congestion and parking.

The patented iStream manufacturing technology of Gordon Murray Design has manufactured new levels of safety and lightweight structure in city vehicles.

The T.27 has an iFrame geometry that allows every aspect of the car to be optimized including Zytek’s integrated powertrain, which is another breakthrough in the world.

During the unveiling of the electric vehicle model at the RAC, Pall Mall, London, Gordon Murray’s CEO -- Professor Gordon Murray – stated that being lightweight is the “most powerful tool” that his company has in the battle against fuel consumption and emissions.

This also helps increase the levels of safety and lessens the retail price significantly. The T.27 is said to represent a big leap forward in protecting mobility and the environment.

GORDON MURRAY DESIGN UNVEIL T.27 – THE WORLD’S MOST EFFICIENT ELECTRIC CAR

29th June 2011, at an event held at the RAC, Pall Mall, London Gordon Murray Design has today unveiled their latest ultra compact city vehicle, T.27, the world’s most efficient electric car.

The design and development programme for T.27 is a £9 million project, made possible through a £4.5 million investment from the government-backed Technology Strategy Board. From a clean sheet of paper to a running prototype the programme has taken just 17 months including the design and build of a completely new electric powertrain by Zytek Automotive Ltd, one of the Consortium partners.

T.27 specifically targets the urban city environment via a unique, holistic, manufacturing process (‘iStream®’) developed by Consortium lead partner Gordon Murray Design, it aims to significantly reduce lifecycle impacts and enable low cost, efficient manufacture within the UK. The electric car sets new standards in weight, footprint, small car dynamics, safety, packaging and efficiency whilst addressing full lifecycle CO2 emissions, congestion, parking and low cost motoring.

Gordon Murray Design’s patented iStream® manufacturing technology has produced new levels of lightweight structure and safety in city cars. The iFrame geometry in the T.27 has allowed every aspect of the vehicle to be optimised including Zytek Automotive’s integrated powertrain, another world first.

On unveiling the T.27, Professor Gordon Murray, CEO of Gordon Murray Design said: “Lightweight is the most powerful tool we have in our armoury in the fight against emissions and fuel consumption. This is true of all cars and especially so with electric vehicles! A lightweight car means a lightweight battery increasing the levels of safety and reducing the retail price dramatically.” The T.27 represents a huge step forward in protecting our mobility and our environment.

Gordon Murray Design recently achieved first class results in a second crash test on the vehicle - the EuroNCAP 50kph mobile deformable barrier (MDB) protocol, confirming the structural integrity of an iStream® manufactured chassis during a side impact.

The real world performance of T.27 closely correlated with simulation revealing virtually zero cabin intrusion during the dynamic phase of impacting. The exemplary performance of T.27 in side impact presents a further milestone in vehicle safety development for the company.

The Consortium also released today the updated specification and performance targets for T.27:

Vehicle Specification

eMotor: 25kW Height: 1.60m
Battery Type: Li-Ion Weight: 680Kg (incl. battery)
Battery Spec. 12kWh Wheel Base: 1.78m
Length: 2.50m Turning Circle: 6.0m
Width: 1.30m
Performance Targets

Top Speed: 105kph
0-100kph: Less than 15 seconds
Range: 100 miles on NEDC, 130 miles on ECE15
In comparison to other electric cars the T.27 has much lower energy consumption per mile, the Smart EV uses 29% more energy per km, the Mitsubishi iMiEV uses 36% more energy per km, and the Mini-E uses 86% more energy per km, making the T.27 the most efficient electric car by some margin.

Iain Gray, Chief Executive of the Technology Strategy Board said: “I must congratulate Gordon Murray Design and their partners for developing the T.27 prototype – and in rapid time. The growing pressure for more environmentally friendly transport, from both customers and regulators, is creating new business opportunities in the fast-developing market for low carbon vehicles. The Technology Strategy Board exists to help drive dynamic technological innovations such as the T.27, which are key to meeting our climate change goals”.

Gordon Murray Design is currently talking to three possible manufacturers for T.27. The car will make its public road debut at the RAC Future Car Challenge on 5th November 2011.
