Auto major Mahindra & Mahindra came out with the biggest investment plan so far, saying it will spend Rs 5,000 crore over the next three years on infrastructure, product development and capacity expansion. The company has also lined up 8-10 new variants and upgrades of its products this year.

However, the spotlight shifted to bike makers such as Triumph, DSK Hyosung and Japan's Terra Motors as they presented superbikes and electric vehicles.

Britain's iconic Triumph Motorcycles expanded its offerings in India with the launch of 'Daytona 675' priced at Rs 10.15 lakh in Delhi.

The new bike is expected to give Triumph a competitive edge in the super sports segment after its entry into the Indian market with 10 models in November last year.

Superbike maker DSK Hyosung, seeking to boost sales by 40 per cent to 2,800 units in 2014-15, launched a 250cc bike 'Aquila 250' priced at Rs 2.69 lakh and showcased the RT 125D, GD 250N and Comet 250, which will be launched later this year.

Japanese electric two- and three-wheeler maker Terra Motors has lined up an investment of Rs 45 crore to expand operations and set up a manufacturing plant. The company entered the Indian market with the Rs 18 lakh Kiwami, an electric superbike.

Mumbai-based Vardenchi launched a bike in the range of Rs 8-12 lakh. The newly introduced motorcycle, Vardenchi T5, is designed and developed at the company's facility in Mumbai, while the engine is imported from Italy-based Moto Morini.

Lohia Auto, which today launched electric-three wheeler Humrahi, is investing Rs 40 crore in the next two years to ramp up its production capacity.

Other auto makers also came out with their plans for environment-friendly vehicles.
