Citroën C-Elysée & Citroën C4 L

The Citroën C-Elysée & Citroën C4 L are two new Citroens aimed at budget compact saloon buyers in emerging markets. The biggest car market in the world is actually the compact saloon, even if Europe, and particularly the UK, has taken to the hatch and compact SUV instead. We recently had the Peugeot 301 arrive as an offering for more budget-minded car buyers in countries like Turkey, Eastern Europe, Russia, Ukraine, Greece, Middle East and Africa, and the new Citroen C-Elysée is the Citroen take on the same objective.

Concept Car of the Week: Volvo Tundra (1979)

With Volvo beginning a new chapter in its design history with the Concept Coupé, it's interesting to look back at another Volvo coupé concept from 1979 – the Tundra. At the time, the Swedish manufacturer built large and relatively pricey cars that were neither really luxurious nor real 'people cars'. The 340 series began the brand's expansion towards more affordable models and proved to be very successful worldwide.

(Another) Audi A3 e-tron hybrid at Geneva 2013

The Audi A3 e-tron – a hybrid A3 EV based on the A3 Sportback – will debut at the 2013 Geneva Motor Show as a concept. This Audi A3 e-tron isn’t a pointless electric supercar – like the R8 e-tron – or another rollout of the A3 e-tron BEV, but a hybrid A3 with a proper ICE engine coupled to an electric motor, just like the A3 e-tron concept we saw in Shanghai in 2011 That still means a lot of complicated and heavy technology to game the silly official economy tests and come up with ‘official’ economy figures of 158mpg and 35g/km, but the A3 e-tron would – if it were made – offer big tax breaks for company car drivers. The A3 e-tron gets a 1.4 litre direct injection petrol engine good for 148bhp working with an electric motor good for an extra 100bhp.
