All are ideal scenarios. Real world scenario, in India, the cheapest core i7 4500U I could find was:-

whereas the cheapest core i5 4200M is
Dell 15R 5537 Laptop (4th Gen Intel Core i7 4500U- 16GB RAM- 1TB HDD- 15.6 Inches Touchscreen- Win8-1 Year Seller Warranty) (Silver) - Buy Online @ Best Price | Snapdeal.com
HP has gone HTC this year and are overpricing their laptops....this is the very reason why this thread was created in the first place. I am not ignoring the fact that core i7 4500U gives a superb battery life but with it comes a huge performance decrease(over core i7 4700MQ) and also a price increase(but less performance decrease if compared to core i5 4200M). For most people 6 hours of battery life is enough and if battery life is the single most important thing one is looking in a laptop then it is advisable to get a macbook air in the first place.
I still don't understand why Dell didn't go for core i7 4702 MQ instead of 4500U even though it is cheaper than core i7 4700MQ and comes with has a good balance of battery life+performance.
BTW Max I have ever done is 60 kph as I am still learning to drive
