192 bhp Insignia BiTurbo

A new diesel engine isn’t always the most exciting development, but the new 2.0 litre CDTI BiTurbo option for the Vauxhall / Opel Insignia promises to offer an appealing blend of power and efficiency.

Based on an existing common-rail four-cylinder unit, the fitment of a second smaller turbocharger helps to prevent turbo lag, which should in turn make for a sharper throttle response. It even gets its own dedicated intercooler to ensure the most effective delivery of air into the cylinders at all engine speeds.

The result is 192 bhp (143 kW / 195 PS) and 400 Nm (295 lb/ft) of peak torque, outputs that approach those of premium rivals such as the Mercedes-Benz C 250 CDI and the BMW 325d. More significantly, it also means that the Insignia can now compete with the 2.2 Duratorq TDCi-equipped Ford Mondeo:

Prices for the Vauxhall Insignia BiTurbo start from £27,120 in the UK. It’s available with a choice of front- or all-wheel drive, Hatch or Sports Tourer body styles, and SRi, SRi VX-line or Elite trim grades.

Alfa MiTo TwinAir arrives

Image
The Alfa Romeo MiTo supermini is now available with the innovative two-cylinder TwinAir petrol engine. Although its capacity is only 875 cc, a turbocharger and the MultiAir electro-hydraulic valve control system mean it produces a respectable 83 bhp (62 kW / 85 PS) and 145 Nm (103 lb/ft) of torque. Performance might not be scintillating - the 0-62 mph (100 km/h) sprint takes 12.5 seconds and maximum speed is 108 mph (173 km/h) - but the TwinAir’s trump card is efficiency. Carbon dioxide emissions are only 98 g/km, a level that brings numerous benefits for UK drivers including zero road tax, a full discount on the London Congestion Charge and qualification for the lowest company car benefit-in-kind rate. Fuel economy is also decent and, according to the official figures, a TwinAir-powered MiTo will manage 67.3 mpg (4.2 l/100km) on the combined cycle. Impressive maybe, but still some way off the 78.5 mpg (3.6 l/100km) of the existing 1.3 JTDM-2 diesel MiTo. However, any

Moto Guzzi V7 Record kit

Image
Inspired by the 1969 V7 Record that set several speed records for Moto Guzzi, the new Record kit has been designed to give current-generation V7 models a retro endurance racer look. Included is a lightweight fibreglass front fairing (which handily uses the existing headlight), plus a replacement single seat unit that features memory foam. The kit can be fitted to the V7 Café and V7 Racer without any modifications. It’s also suitable for the V7 Classic, V7 Special and V7 Stone, but a set of Moto Guzzi clip-on handlebars will be needed as well for those variants. Priced at £1,399.99 in the UK, the Record kit is available from dealers now. Related post: Moto Guzzi Corsa special
