Carmakers will have to cut sports car noise

Mercedes-AMG CLA45 S — be quiet, now.
The snarly sound of most sports-oriented cars is one of the attractions to buyers, but the EU figures that doesn't help the quality of life of those on the street who have to hear it, writes Brian Byrne.

So a new regulation aims to trim back the current maximum permitted noise levels from cars. At the moment that is 74 decibels, but the regulation will have it down to 68 decibels by 2026.

Carmakers are taking note. One option is to have artificial exhaust notes, working through the car's audio speakers. But the Mercedes-Benz AMG division is staying natural, routing the sound directly into the cabin before muting it as the exhaust expels through the tailpipes.

So, for pedestrians and cyclists and other audio-unprotected road users, the 'snap, crackle and pop' of the super sports cars will in future be only in their Rice Krispies.

Opel continues its electrification offensive with the Vivaro van to also be offered in a pure battery electric version as of 2020, writes Trish Whelan . The Vivaro-e extends Opel’s range of particularly efficient light commercial vehicles. Customers can then choose between two sizes of battery, depending on their needs: a 50kWh battery for a range of up to 200kms or a 75kWh battery for up to 300km (according to WLTP). With emission-free deliveries becoming increasingly important in urban areas, the demand for purely electric light commercial vehicles will increase accordingly.   The Vivaro-e is based on the group’s variable MP2 platform which enables the use of conventional as well as electrified powertrains. The Opel Vivaro No. 3 is available in three lengths instead of two (4.60 metres, 4.95m and 5.30m); has a 200kg higher payload of up to 1,400kgs and can pull half a ton more (trailer load up to 2,500kg). Most versions of the new Vivaro are also o...

Gambar
Christmas is the season of office parties and catching up and celebrating with friends and family. However, over-indulging the night before can mean it is easy to have alcohol in your system the next morning. Over 1,000 arrests for drink driving were made over the Christmas period last year and the new laws which came into effect over a year ago mean that first-time drink-driving offenders will be automatically banned from driving for three months if caught with between 50 - 80 milligrams of alcohol per 100 millilitres of blood, equivalent to 0.22 - 0.35 milligrams of alcohol per litre of breath. Previously, drivers caught at these levels received three penalty points and a fine … but no driving ban. Now you can test yourself the next morning with the AlcoSense Lite 2 digital personal breathalyser. Designed in the UK by racing driver and businessman Hunter Abbott, it gives you clear results in seconds. All you need for a reading is to turn the unit on, wait for ...
